OK, so the gorgeous yellow-orange Fairburn was the highlight of my rockhounding trip this weekend, but it certainly wasn’t the only “find”. Here’s a selection of some of the other agates, jaspers, etc. What amazes me about this location on the Buffalo Gap National Grasslands is the seeming infinite variety of what you can find, all within one very small area. All of these were collected within a one-square mile area.
Been stressful at work lately so I took off Friday and did something I’ve only done one other time this summer…head out to the Buffalo Gap National Grasslands and go rockhounding. It wasn’t the most pleasant of days! The forecast called for 75 and cloudy, but when I got about 60 miles away, the fog started getting thicker and thicker, and soon it was accompanied by a light drizzle. Much to my chagrin, things were exactly the same at my favorite rockhounding spot southwest of Kadoka. I ended up rockhounding from about 8 AM to 2 pm, and the temperature never got higher than 60, with the drizzle falling most of that time.
I found plenty of “good” material. As many prairie agates as I could want, as always. Bubblegum agates. Quartz. Petrified Wood. Jaspers. Adventurine. But the “prize” for people searching out there is a Fairburn agate. Since we started doing this last summer, we’ve probably been out there about 8 times, and have found a Fairburn about half the time, and that’s with a good, hard days’ search each time.
As the drizzle was just thick enough to make you a bit miserable Friday, I was contemplating leaving. But as I paused for a second to assess my situation, I saw a bright yellowish-orange stone ahead of me, one that really stood out from the others around it in terms of the color. Much to my delight, as I approached I saw some fine parallel banding…Fairburn! And a pretty good sized one, at over 2 inches in length. I did continue rockhounding for awhile before returning to the car and getting a good look at the banding.
A find that made a miserable weather day a whole lot brighter.
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?
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.
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.
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.
On Labor Day I again made the long trek to the Buffalo Gap National Grasslands of western South Dakota, a day to look for agates, fossils, petrified wood, and other goodies. For the first time since we discovered rockhounding this summer, there were actually a number of other people out searching. You can see how the known agate hunting locations would get picked over. However, it’s quite similar to a visit to a busy national park like Yellowstone or Yosemite…just get away from the road a bit and you’re likely to have it all to yourself.
Despite several other searchers, I was able to find solitude just by hiking back away from the gravel roads in the area. There’s no doubt there are more and better finds as you get away from the roads and places people park. An interesting day, marked by a heavy haze all day from western US forest fires, but also a day filled with agates. Here are a few agates from the day. Also the latest batch that’s gone through my polishing. I’ve pretty much got it down now, and can get a real deep shine, but it’s a 2-month process from start to finish! Always good to finish a batch and see what you get for all your hard work.
I have a new hobby! I got a new lens 2 summers ago. It’s a very high quality lens that enables some truly stunning, clear, crisp photos, but I just haven’t used it very much since it’s quite a bit different lens than the one I use to shoot birds. Today I thought I’d give it a whirl, and in doing so, I may have created a new hobby for myself…taking photos of the planets!! I was able to take photos of 12 different planets today, all while out on my back deck! Yeah…yeah…THAT’s right… I took photos of TWELVE different planets, in the space of only about an hour.
Well…OK…they may LOOK like planets, but I’ll fess up…they’re not. I put my rarely used macro lens on my camera this afternoon, and started to take some documentary photos of some of the agates and other stones that my son and I have found over the last month on the Buffalo Gap National Grasslands here in South Dakota. After taking a few extreme closeup photos of one of our favorite agate finds, the composition of the photo, with the curve of the agate and the shadow behind it, made it look like a photo of a portion of a planet. I really loved the look of the macro shot, and just went with it, setting up other agates and trying to get “planetary agate” photos. Here’s a collection of some of our favorite agate finds from the last month…
