Bubblegum Agate - South Dakota Rockhound

An incredible, polished bubblegum agate from the Buffalo Gap National Grasslands of South Dakota. An amazing little piece, it was a small, black, featureless lump when we found it, but we’ve found that these little dark bubblegums often have some GORGEOUS patterns that reveal themselves once you polish them for a while. There are other examples on the updated pages on South Dakota Rockhound pages.

I’m 51 years old. I already have so many unprocessed bird photos sitting on my hard drive that I doubt there are enough years left in my life to process them all, and add them to my website or blog. It’s easy to take photos!  It’s FUN to take photos!  It’s much less fun to process them all and DO something with said photos.

And now my son and I have a new hobby that we started last summer…rockhounding in the incredible areas near the Badlands of South Dakota. We certainly have found some beautiful pieces of agate, jasper, petrified wood, and other stones over the last year.  The wonderful and variable patterns and colors just BEG a photographer to get out the camera…I can’t resist!  As if I needed more unprocessed photos cluttering up my hard drive, now I’m also taking macro photos and photos of rocks and minerals, many of which will likely never see the light of day.

I’m trying! I’m trying to be more selective in what I shoot, both for birds and for rocks!  And in an effort to at least get some photos of my favorite pieces out on my website, I have just recently updated the “South Dakota Rockhound” section of my website.  Click on the following for photos of some of the pieces we’ve found over the last year. There are also some cool macro photos of other mineral assets we’ve acquired over the past year (for now, just a batch of Mexican Crazy Lace agate).  As with the birding pages on my website, I’ll try to continually update the Rockhound site as I have time!  For now, enjoy the new photos.

Mexican Crazy Lace Agate - Macro Photograph

A macro photo of one of the pieces of Mexican Crazy Lace (agate) we bought recently.

Pondering Petrified Wood

Human beings are funny creatures. When we see something, we immediately want to categorize it.  For a birder, identifying and tallying species is a huge part of the hobby. For my work as a scientist working with satellite imagery, my task is to categorize the types of land cover (cropland, urban, deciduous forest, etc.) on the earth’s surface.  For a rockhound?  I’m struggling with identification as a rockhound newbie, just as I did 20 years ago when I was a birding newbie.

Petrified wood is one category of material I thought was easy to identify. When I’m out on the Buffalo Gap National Grasslands, there is a LOT of petrified wood lying around. By that, I mean there’s a lot of easily identifiable pieces that look exactly LIKE wood, with obvious grain patterns.  But as with anything in life, it’s not that easy.  Below are some of the obvious, and not so obvious pieces I’ve found on the Grasslands. Thoughts? Are all of these petrified wood?

Petrified Wood - Buffalo Gap National Grasslands, South Dakota

First, an obvious piece of petrified wood. This is what I find the most of…gray exterior pieces with clear grain patterns, some of which are so detailed they look like fresh pieces of wood.

Petrified Wood - Buffalo Gap National Grasslands, South Dakota

Another obvious one. Both of these first two pieces have also been tumble polished to a nice shine.

Potential Petrified Wood - Buffalo Gap National Grasslands, South Dakota

And this piece? This is the most colorful piece I’ve found, for something that’s possibly petrified wood. You certainly see a linear “grain” running throughout. Petrified wood? Perhaps an agatized petrified wood?

Potential Petrified Wood - Buffalo Gap National Grasslands, South Dakota

Same piece as above, except on the flip side. Again, you see the grain pattern throughout.

Potential Petrified Wood - Buffalo Gap National Grasslands, South Dakota

A less obvious one. The photo doesn’t show it as clearly as what you see through a loupe, but there are rough “grain” patterns. They’re more little streaky nodules all oriented the same direction. I know there’s petrified palm that can be found in this area, but I don’t know what exactly the palm looks like from this area.

Potential Petrified Wood - Buffalo Gap National Grasslands, South Dakota

A similar one, with little linear nodules lined up in the same orientation like a wood grain (again, a bit hard to see in this photo).

Potential Petrified Wood - Buffalo Gap National Grasslands, South Dakota

The photo of this piece does a better job showing the type of “grain” seen in the previous two pieces as well. Obvious, and all oriented in the same direction.

Macro Mania

As a bird photographer I don’t put on my macro lens very often, but I got it out this afternoon to take some macro photos of the batch of Mexican Crazy Lace agates that I got this past week. Before I started tumble polishing them, I wanted to record what they look like in their natural state. When you zoom in extremely close like this, you can really see the beauty. It boggles my mind that these gorgeous patterns are all made by nature…such variety, such cool patterns, such wonderful colors.

Crazy for Mexican Crazy Lace!

Already, now I’m in deep. Since we started rockhounding and polishing this summer, It’s all been focused on self-collected material. Nearly all of that has been done on the Buffalo Gap National Grasslands in western South Dakota. Now, for the first time…I (gasp!) actually PAID for a box of rocks. Sure, it wasn’t much…$4 a pound, for 5 pounds of rocks. But I’ve crossed a line now, where it’s now fair game to pay hard-earned cash for rocks.  It started when I was on a rockhounding website, and I saw someone who had just gotten a bunch of “Mexican Crazy Lace” agates to tumble polish. It’s a kind of banded chalcedony, found (surprisingly!) in Mexico, in the state of Chihuahua.  Such gorgeous, gorgeous material that tumble polishes very well…I had to have it! Here are some of the raw, un-tumbled pieces that came in my first ever purchase of a box of rocks. Check back in about, oh, 2-3 months, and I should have these polished up!

New Polished Batch – Best Yet!

There are two moments in polishing stones that are akin to Christmas morning for a kid.  One is after the first rough polish. It’s at that stage where you get some wonderful hidden surprises, where the rough polishing has removed outer material and exposed some beautiful patterns underneath (happens a lot with bubblegum agates, for example).  The second big moment is taking a batch out of the final polish. It’s a long process to polish rocks!  I’ve learned patience, and it’s usually a two-month process to go from rough material, to a beautiful, shiny final product.  Here are photos of the latest batch…my best yet, without question!  A wonderful mix of agates, quartz, petrified wood, and jaspers.   And the best aspect of this batch…EVERY piece was self-collected, on the Buffalo Gap National Grasslands here in South Dakota.

Polished agates and Stones - South Dakota Rockhound

An overview of the final batch. In this batch, I included a wide variety of stones, including many different agates, petrified wood, quartz, and jaspers. The one thing they all have in common…they all came out WONDERFULLY shiny!

Polished Fairburn Agate

A surprise! This is one of those agates where there’s a surprise underneath a weathered outer layer. I suspected there might be something special underneath the heavily weathered exterior of this piece. There certainly is…the beautiful, fine banding of a Fairburn agate.

Bubblegum Agates - Polished

Typical bubblegum agates. Once polished, most seem to show the reddish and cream colors of the agates shown here. Once the little eyed nodules wear down in the polishing process, you can get some truly gorgeous colors. Best of all, bubblegums take a VERY good polish and shine.

Petrified Wood - Polished

This is the most common form of petrified wood that I’ve found on the Grasslands. You do have to be careful polishing, as sometimes the wood pattern is only on the exterior of the piece and may wear away if you polish too much. If you’re careful though, you can get a beautifully polished piece such as this.

Polished Bubblegum Agate

This is small piece, the diameter of a penny. But HOLY COW do some polished bubblegum agates look wonderful when polished. In this case, the entire outside of the bubblegum was black when I first put it in the polisher. Many times that black wears completely off, often leaving the typical red and cream colors of bubblegums found here. On this one, I stopped the rough polish while it still had some black “eyes”. Gorgeous little piece.

Polished Gray Quartz "Egg"

There are pieces of quartz on the Buffalo Gap National Grasslands of many different colors. This smoky gray piece polished up beautifully, particularly after I left it in the rough-polish stage for many weeks to get the “egg” shape.

Polished Red Congomerate / Jasper

I don’t know what to call this piece, but it’s freakin’ gorgeous! It’s pretty much one-of-a-kind for pieces I’ve found on the grasslands.

Heavily banded agate - Polished

Most of the prairie and bubblegum agates you find have some form of banding. Many have some very fine bands. But this piece has more “layers” of thin banding than most pieces, and it has some incredibly beautiful colors as well. It’s got an unusual shape, and I was tempted to keep it in the rough polish phase for several more weeks to get a more rounded shape. Given how beautiful it is, however, I didn’t want to take a chance it might break apart, so did the final polishing on this unusual shape.

Polished Quartz Variety - South Dakota

Some of the polished quartz pieces from this batch. Clear, White, and pinkish tones are the colors you find the most, but there are others as well. ALL polish up beautifully.

Polished South Dakota Agate - (Fairburn?)

Another agate where the pattern underneath really wasn’t revealed until after many weeks of polishing. It’s not as obvious as the Fairburn above, but there are some hints of a Fairburn-type pattern.

Polished mossy agate - South Dakota

I know there’s a kind of agate called “mossy agate”. I’m not sure that’s what this is, but it’s such an unusual piece. The pattern itself is quite unusual for agates I’ve found, but so is the mossy, orangish patterns that fill in the gaps between the white blobs. Cool one-of-a-kind piece in my collection.

Polished Prairie Agate - South Dakota

From an unusual piece above, to a pretty common piece. While creamy and white banded prairie agates are the most common color form I seem to find, I also often find ones like this, with blackish bands in a creamy matrix.

Colorful Petrified Wood - South Dakota

The grayish petrified wood near the top of this post is easy to find, but you do also sometimes find more colorful pieces. This one has some wonderful reddish tones, as well as a bluish streak on the back side.

Polished South Dakota Agate

I kept putting this pieces back through the rough-tumbling phase, trying to wear a bit more off of this side to try to reveal more of the different colors. But alas, it kept getting smaller and smaller, but with the same color pattern.

Polished South Dakota Bubblegum Agate

Another great little bubblegum agate. Some of these pieces end up showing many little eyes once polished, but many also often show some gorgeous banding underneath.

Petrified Wood - South Dakota

Some of the petrified wood in this batch, showing the variety of forms you can find on the Buffalo Gap National Grasslands.

Polished South Dakota Conglomerate / Prairie Agate

I’m not sure what you call this…a prairie agate, or some kind of conglomerate. Prairie agates here seem to often be banded, but some too do look like a mish-mash of fragments that have been found together. The conglomerate-looking ones really can have some cool patterns once polished.

Polished South Dakota Conglomerate / Prairie Agate

Speaking of funky conglomerate-like stones…this one has some very fine patterns that are pretty unusual compared to other pieces I’ve found.

Polished Quartz - South Dakota

The biggest piece in this batch, an almost tennis-ball-sized chunk of quartz with an cool brownish-orange tone intermixed throughout.

Polished bubblegum agate with "eyes"

Sometimes bubblegum agates turn out like this when polished, with just the “eyes” remaining.

Small polished prairie agate

Size doesn’t matter! Even the small little pieces have some gorgeous patterns once you photograph them in macro mode.

Polished Red Splotch Agate

I call this “red splotch agate”. Given I’m still new at this and have no idea of what to really call it.

Polished Red Prairie Agate

Some of the prairie agates have reddish tones, but this one has more red throughout than most that I find.

Reddish polished quartz

Another of the reddish quartz pieces.

Polished South Dakota Quartz

And…one last one, another polished piece of quartz.

One more trip – Rocks and Birds

It was a beautiful weekend in much of South Dakota, so much so that the lure of one last rockhounding trip was too much for me to pass up.  With projected highs near 60, and just as importantly on the windswept plains of South Dakota, a lack of a wind, it seemed like the perfect day to roam around the Buffalo Gap National Grasslands. An added treat of birding the western part of the state at this time of year…all of the winter raptors that are arriving!

I started out rockhounding, and could tell it was going to be a great day.  I tried a little bit different spot, and immediately found it wasn’t as “picked over” as my typical spot near Kadoka.  Right away I was finding many bubblegum agates, some beautiful rose quartz, some amber-colored honey agates, prairie agates, and some big chunks of petrified wood. I also found several coral and shell fossils, including one cute little bubblegum agate with a crisp imprint of a shell on the back side.  The highlight…after only 10 minutes, I found a gorgeous Fairburn agate with an unusual, rosy-colored quartz center.  That piece alone would have made the trip worth it.

While I spent most of the day rockhounding, I also kept my eyes open for the arriving winter raptors. Rough-legged Hawks, as always, were in abundance in parts of the Grasslands. Ferruginous Hawks, Golden Eagles, a prairie falcon, and plenty of Red-tailed Hawks rounded out a day that finished with the spotting of a gorgeous, pure white, unbarred Snowy Owl on the drive back home. A great “last blast” out on the Grasslands, before the really cold South Dakota winter hits.

Fairburn Agate - South Dakota

A gorgeous Fairburn agate as I found it on the Buffalo Gap National Grasslands. On average this year, I’d say I find one Fairburn for about every 15 hours of looking, so it’s always a wonderful treat. This one was so unusual, in terms of that grogeous rosy center surrounding by the fortification banding.

South Dakota Agates, Jaspers, Petrified Wood, Quartz

The material I brought back. You can collect on the Buffalo Gap National Grasslands, but 1) only for private collections (no selling of material), and 2) can collect up to 25 pounds of material in a day. Given I usually only keep the smaller pieces (most are 2″ or less), that’s not a problem! But on this day, there were some BIG pieces of petrified wood I was tempted to bring home! If I had done so though, a couple of them would have used up my 25-lb allotment! Hence sticking with my “usual” agates and other material.

South Dakota Rockhounding Display – Complete!!

The age-old question has been answered!  The question (primarily from my wife)…”What are you going to do with all of those rocks?” Minor detail, something I hadn’t thought about much since my son and I started rockhounding this summer!  But given the growing collection in the basement, it was time to figure out how to display some of our goodies.

It’s been a labor of love, but it’s now complete!  Over the last couple of weeks I’ve refinished the printer’s trays I got on eBay, and installed them on the wall of my office.  Given how new we are at this, we still don’t have a huge number of pieces that have made it all the way through the tumbling and polishing process, but we certainly have PLENTY of combined raw and polished material to fill the 178 individual compartments in the two printer’s trays!  I think they look fantastic, and certainly add some wonderful character to my home office!  Here are some photos:

South Dakota Rockhounding DIsplay

The finished printer’s trays, sanded and refinished on the wider cross pieces, but simply cleaned up and left as-is for the individual compartments themselves. I used a brown enamel paint on the wide pieces, but simply sanded off the old paint and expose the metal faceplate on each drawer. The most satisfying aspect of the collection shown here? Every single piece was hand-collected by my son and I, all from right here in South Dakota!

South Dakota Rockhounding Display

An oblique view, one that shows the bare metal I left on both original drawers.

South Dakota Rockhounding Display - Agates!

For each of the two printer’s trays, I cleaned up the original drawer pull, and repurposed them as labels. The right side is rightly labeled “South Dakota Agates”, as every piece on this side are prairie, Fairburn, bubblegum, or other agates, all collected from the Buffalo Gap National Grasslands.

South Dakota Rockhounding Display - Jaspers, Petrified Wood, Quartz, etc.

The original drawer pull and label on the left piece. This side is more of a “mish-mash” of material, with a lot of petrified wood, quartz, chalcedony, jaspers, and other pieces. Again, all collected from right here in South Dakota!

Prairie and Fairburn Agates - South Dakota Rockhound

One of the six major compartments across the two trays. This one is devoted to prairie agates, and the handful of Fairburn agates we have so far.

Fairburn Agate - South Dakota Rockhound

We haven’t found many Fairburns as of yet, but the one on the right here is the favorite of ANY piece we’ve found so far.

Bubblegum Agates - South Dakota Rockhound

One of the six compartments devoted to bubblegum agates. Some are tumbled and polished, most here have not been polished yet. I like the look of the little bubblegums though, and probably won’t polish most of these. The “eyes” of the bubblegum agates give them a great look then when you do polish.

Bubblegum Agates - South Dakota Rockhound

A closer view of some of the “raw”, untumbled bubblegum agates. You can see why they are well named! They do often look like chewed up pieces of bubblegum.

Petrified Wood - South Dakota Rockhound

The 2nd most common find for us on the Buffalo Gap National Grasslands – petrified wood. These are all petrified wood pieces. Most you find are the grayish or tan color, but there are also some other beautiful colors and patterns you can find. Most of these have not been tumble polished.

Chalcedony and Chert - South Dakota Rockhound

It’s not just agates and petrified wood on the Grasslands! There are other forms of chalcedony, and a huge variety of other rocks as well. I’ve been told those on the right (particularly the bottom right) are chert, in a limestone matrix.

Miscellaneous Prairie Agates - South Dakota Rockhound

A closer look at some miscellaneous (prairie) agates. There’s quite the variety of colors and patterns that you can find.  All here are polished, except the one in the upper right.

Misc. Jasper and Quartz - South Dakota Rockhound

A few miscellaneous jasper, quartz, and agate.

Large agates, chalcedony, etc. - South Dakota Rockhound

The only downside to the use of the printer’s trays…some of the compartments are relatively big, but the depth is quite shallow. Bigger pieces thus won’t work. I haven’t quite decided how I want to display them, but for now I have a table directly underneath the display, and I’ve started to put out a few big pieces. These are some big chalcedony pieces, prairie agates, and petrified wood.

Printer’s trays – For rock/mineral collection

It’s been about 5 months since my son and I started rockhounding, and polishing some of our finds in a tumbler. It’s rather shocking how much material you can find on the South Dakota grasslands in just 5 months! I’ve got several large trays and buckets worth of agates, jaspers, petrified wood, fossils, and other goodies. Now the number one question I get from our other household member…”What are you going to do with all of those”?

It’s a DAMNED good question!  I’ve already taken over our utility room (the room downstairs with the furnace and water heater).  A big wire shelving system is chock full of rocks and supplies, and two tumblers have been going non-stop for the last 4 months. It’s such a long process to polish, that we don’t have a massive number of “final” pieces, but it’s a growing amount.  Nearly all right now are either sitting on a shelf at work, or are sitting unseen in a tray in the utility room. Lately I’ve been looking at ways to display them.

I came across some images on Pinterest for displaying collections, including a guy who used “printer’s trays” to display his cork collections. I had never heard of a printer’s tray.  They are large wooden trays with many small compartments, used by letterpress printers to hold the tools of their trade.  Not knowing where the heck you could possible get such a thing, I looked on eBay and was surprised to see many available.  One person was selling several quite cheap (only $22 each!), so bought a pair and thought I’d see what I can do with them.

They look wonderful! They’re old and have an antique look to them, but are in really excellent shape. I’m not quite sure how I’ll use them yet, in terms of whether I try to do some kind of refinishing on them, or leave them more as is.  Stay tuned…within the next few weeks I hope to get a nice display set upon the walls of my home office!

Printer's Trays

The two printer’s trays I bought on eBay. Not what they are designed for, but they are truly wonderful for displays of small knick-knacks! For me, that means agates and other geologic goodies. They even came with the original grass drawer pulls! Once I decide whether I want to do something to the finish, I plan on hanging them vertically (kind of similar to this) in my home office.

Christmas in October!

I think my favorite part of tumble polishing stones…taking them out from the first time they enter a rough polishing phase. Many at that stage are odd shapes, dirty, or where I collect them, are covered with a blackish or grayish layer after being exposed to the elements. It’s when you get them out of the tumbler after the first rough polish that you start to see the hidden beauty underneath.

Here’s part of a batch fresh out of the tumbler! Woo-hoo…some WONDERFUL surprise October presents!  These all were collected in the same 1-square mile area on the Buffalo Gap National Grasslands. Yes…you find this incredible variety of agates and other stones, all in one spot!  Rockhounding nirvana.

A couple of pictures. The first shows what they look like wet, and gives a hint of their final glory.  The second shows them in their dry, current stage.

South Dakota Agates and Jaspers

This is what the agates and jaspers look like wet, after the first tumbling stage. When wet you get a good idea of what they’ll look like when they finish polishing.

South Dakota Agates - Rough phase

Part of a batch of South Dakota agates and jaspers, just out of the first tumbling stage. In this stage, the point is to try to shape them, get off the sharp edges, etc. They don’t even start to show any hint of that glorious, shiny luster they’ll eventually have, but even at this stage…they’re gorgeous!

Beauty in Small Packages

Three months. I’m learning the value of patience with my new rockhounding and tumbling hobby, as I’ve learned the stones I tumble (South Dakota agates) are very hard, and need to be tumbled for a long time to get a good polish. I’ve learned that the process thus takes about 3 months!  I was doing one week for each of the four tumbling steps I do, but wasn’t getting great results until I upped that to three weeks for each step.

I’m pretty thrilled with this latest batch!  I would say this is my first real, high-quality batch that I’ve done.  These are from my small tumbler, and thus, most of these stones are only 1″ to 1 1/2″ inches in length. They’re beautiful even to the naked eye, but I’m finding that the use of my macro lens and a close photo really allows me to see the beauty and detail in these stones.  Here’s a (large!) number of photos of various agates and jaspers from my latest batch.

Bubblegum Agate

This agate had the typical, bumpy, bubbly shape of a bubblegum agate, but when I found it on the Buffalo Gap National Grasslands, it was a dull grayish-black. It took the better part of 4 months worth of tumbling to wear down the outer layer, exposing some of the most beautiful patterns I’ve seen on any of my agates.

South Dakota Agate

I’m calling this one “Crystal Dragon”. Not sure whether you’d call this a prairie, bubblegum, or other agate, but I love the swirling pattern, with the crystal/druzy “neck” on the dragon, and a little pink tongue and eye.

Prairie Agate

A prairie agate, showing a beautiful array of colors. A lot of the more weathered agates on the grasslands have black parts on their exterior. I believe that’s manganese oxide that forms when they’re exposed to the elements (at least some of the blacker agates). Much of the time that black disappears when you tumble, but on this prairie agate, the black was maintained in some of the bands.

South Dakota Agate

Wonderful fine detail that’s not all that noticeable to the naked eye, but is quite evident in a macro photo of this agate.

Prairie Agate

A lot of the bubblegum and prairie agates you find have a very subtle, very fine banding such as this. Very often it’s not noticeable until you tumble.

Bubblegum Agate

A classic bubblegum agate, a little larger than many of the agates on this page. Bubblegum agates really tumble beautifully, as you generally get these beautiful agate “eyes”.

Prairie Agate

Interesting shape on this agate, with a little peak that has it’s own little cap/color pattern.

Prairie Agate

A prairie agate, with a lot of “druzy” (crystally) elements.

Prairie Agate

The biggest agate in this batch is also one of the most gorgeous. This beautiful Prairie Agate has some wonderful banding patterns, and a beautiful range of colors.

Bubblegum agate

Another bubblegum agate with the typical eyes you see when polishing.

South Dakota Agate

I’m not sure what to call this one (help!!). It has a definite linear “grain” pattern, but it’s so unlike all the petrified wood I’ve found that I hesitate to call it that.

Prairie Agate

I love the pattern on this one, with the bold orange streak.

South Dakota Jasper

Jasper? Agate? I dunno. Has a pretty pattern though!

Prairie Agate

The most common prairie agate patterns are jagged, rough striping, but this is also a relatively common type of pattern and color for prairie agates from Buffalo Gap.

Bubblegum Agate

Another polished bubblegum agate

Prairie Agate

A prairie agate with some nice banded patterns

Prairie Agate

I love the contrasting patterns on some of the agates, with very dark sections contrasted by white or very light sections.

Bubblegum Agate

Another bubblegum agate, one that was tumbled awhile and didn’t maintain the “eyes” as much as some of the others.
