Destructive collecting

This past weekend I took Little Guy to find a carnelian. One of the iphone apps I have gave directions to the site, which took us about an hour and a half to reach. It was a nice drive and to my surprise Grim and Mandy had decided to tag along. Upon reaching our destination we were confronted with signs that made no bones about how the property owners (a tree company) felt about looking for said rocks. I was pretty surprised, until I started to take a look around. Almost very bend I could see in the creek had huge areas dug out along the banks. The hills beside the gravel road also showed massive amounts of destruction from individuals digging away the sides. Further up the creek piles of rock and mud were evident from screening and dredging for these rocks. Since when is mining activity attributed to a "hobby"?

I came across two locals on horseback and they told me that the area used to be a madhouse on the weekends with groups of people who identified themselves as being from rock clubs. While not all bad behavior can be directly attributed to these types of clubs, I do think they bear a big part of the responsibility for the site being closed. To overtax an area with too many people can take a huge toll on the locals who live in the area and want to enjoy some peace and quiet over the weekends. Not capping arranged trips to a certain amount of members can result in chaos and possibly bad behavior due to competition for getting that "rock". I've seen it happen before at other sites when there is too little room, too many people. Total madness.

In addition, if you are using mining techniques to get said rock, you are no longer a hobbyist- you are a miner! Buy a plot of land and mine it, but don't ruin rock collecting for those who like to casually walk streambeds and pick up rocks already exposed. At the very most, only digging out a rock that is half in/half out with a rock hammer. But to tear away a creekbed, adding to the sediment load.. bad! If you can remove a rock and it makes little to no visual difference, then that is a hobby or getting a rock sample. But if you are removing massive amounts to the point an entire bank is cut away, you are destroying the environment!
So thank you very much greedy people- you just effectively ruined one of the few FREE & educational activities I enjoyed with my children. At least for that area. I'm sure if this continues unchecked, more and more sites will become off-limits.

Meteorite Men

I am so addicted to this show! I think I like it so much because the two guys showcased on the show, Geoffrey Notkin and Steve Arnold, remind me a lot of those I have been in the field with before. There is always a quirky person in every group, you know the one- he is chasing butterflies (or gathering tree sap- yes, tree sap) instead of measuring strike and dip on the outcrop you just climbed 200 ft to find and have yet another ridegback in the distance to conquer. It's tough to keep your temper at them, but they are just so darned puppy-ish you can't chastise them for fear your temper will boil over so you keep it all inside to protect his feelings. (Or at least for me). Then you have the guy who dresses like Charles Darwin (not sure what to say about that one) but he was smart so you don't really care how he dressed, you just wanted him on your team because he got things done. And then there is the loner who works on the outskirts of the group, but once you get to know them you find out they are a MENSA member and while not really as well-versed in geology as you would like, their sharp wit and sense of humour make you laugh at yourself. It's always a good thing to remember to laugh at yourself. :)


So as I watch this show, I see little nuances of the quirky things I have seen exhibited from people out in the field before and I feel strangely comforted. I think perhaps it is because I miss my motley group of friends that I have gathered. It's always tough to move away from people you admire and conspire with, especially for me when it comes to geology. When I watch this show it just flat out makes me laugh. The two of them [Geoff and Steve] banter at one another just as I have done with my friends out in the field, and they enjoy busting on one another as friends tend to do. (I would have had a field day teasing them about the snake boots- the only person I have ever seen wear a pair of those was the Charles Darwin guy, so yeah, um... yeah.). Not saying it's a bad thing to wear them, it just hasn't been a common practice in my experience so I would find it a bit funny. Plus Geoff takes forever to get ready once they arrive at the spot. Every geology trip I have ever been on we pile out of the van as if  we were told it was about to explode. If anyone lagged as Geoff does to get ready they would find themselves quickly alone wondering where everyone had gone off to. Unless it was an outcrop stop, at which point by the time he was finished everyone would be piling back INTO the vans. ha ha. So I enjoy watching him fiddle with getting his snake boots and gloves on as Steve is off and running. 

While the meteorites they find are pretty cool too, once they make their finds I usually prefer the part when they take it to the guy to put in the mass spec. I have to say they are quite talented in finding their treasures, and they are pretty clever in how they go about choosing sites to explore. 


If you haven't had a chance to see this show, I really encourage you to check it out

Badlands road trip 2007

In 2007 I took a special topics course on fossils in the Badlands. This required a road trip across a few states to Interior, SD., and accommodations/travel were the responsibility of the student. A few people were those who made the jaunt every year it (class) was offered, some bringing their older kids, so I arranged for my daughter Brittney to come along with me. She had never been on any previous geology trips, and when I posed the suggestion to her she was very excited about the idea.

The trip out there was a lot of fun. Britt took tons of pictures, as the scenery was far from boring! We passed giant sculptures of dinosaur bones and bulls in pastures, beautiful lakes and hills, and the weather was absolutely lovely. Upon reaching our destination there is an astonishing change in geology. My breath was taken away by the effect. I can only imagine what the early settlers thought when they came upon the barren landscape that I found so beautiful. It was surely the antithesis of what I felt upon seeing the colorful layers of earth exposed from years of erosion.

The town itself made me smile. It reminded me of my little village back home in Alaska. What really made me fall in love with the place was when we stepped into the little cafe and everyone stopped talking to turn and look at us. My daughter was horrified, but I belted out the biggest smile before I could stop myself. I felt so at home! It was all I could do to keep from chuckling at poor Britt, as she is a through and through city girl and wasn't used to their curiosity; instead interpreting their behavior to mean they didn't appreciate strangers. I had to explain to her that when you live in a small town and someone new arrives, you cannot help but stare. It's like drinking a cold glass of water after being parched. After getting directions to the campsite from them (and once they knew what I wanted they were pretty much falling all over themselves to offer help and were very chatty:) we were on our way to the campsite. I love small quirky towns!

I had reserved a cabin at the campsite the class was meeting at and it much nicer than we had anticipated! It was a bit secluded, so we weren't really included with the rest of the group a lot, but this also allowed for us to just enjoy our time together. The itinerary began with heading out early the next morning towards Wall. Speaking of Wall, this is another cool town- a MUST see for anyone! Britt and I had so much fun there, I think my side was splitting from laughing so hard. There is a big "Triassic Park"- like dinosaur that appears innocuous at first, only to light up growl and charge towards you. The normal person wouldn't have been bothered by it, but I about peed my pants because I was just standing there and didn't expect it to move. LOL. It was so silly of me I think the two of us laughed about that for a good 10 minutes. There were a lot of fun shops to browse through, and it was just generally a lot of fun. Very tourist-laden, but worth the trip!

Now back to that first morning in the field.. it was very cold and it had started to rain, so we had to park the vehicles at the top of the hill, limiting us to a small area. The rain saturated the upper crust of the hills (which were deceptively steep) so when you took a step and lifted your foot, a 3 inch rim of mud was clinging to it and increased with each step you took. While I didn't slip, quite a few others did, prompting the professor to cut the day short. Our second day out proved to be much more fruitful. It was still cold, but the rain stayed off in the distance. The earth dried into a crumbly texture, so care still had to be taken when walking up the steep slopes. Again, they were deceptive in how steep they were. It didn't seem steep until you were up on top of them looking down.

Britt stayed close to me, and helped me brush away dirt when we found a fossil here and there. (She pretty much just stayed crouched in one spot watching me work, re: picture, left).  At one point I had spied a tooth, but when I went to reach for it I started to slide down the embankment prompting her to yell at me "Use your rock hammer!", which I did, in order to stop myself. Once I came to a stop I just stayed there for a second, but looked over at that darned tooth! Knowing me as she does, Britt says in her best deadpan manner, "Don't do it." LOL. I had to chuckle to myself when she said that. I wouldn't have grabbed for it, but can't deny the thought hadn't run through my mind. The drop was a good 80-100ft. and were I to fall we were in a remote area that wasn't easily accessible. So I just scooted back up to where the ledge evened out a bit and then sat back up and forgot about the tooth.

During this trip, we were also able to visit a rose quartz mine, see a pegmatite, and a quick trip to Mount Rushmore. Additionally, we were able to browse through the SD School of Mines museum which had beautiful displays of rocks, minerals, and fossils. It was a trip we both really enjoyed, despite the wet and cold conditions. Since then Britt has become quite talented at knowing what types of outcrops I like pictures of, and she will click away as I drive. In fact, she took the picture of the main rock outcrop I used in the title logo of this blog. If you look closely you can see a bit of the reflection from the window (on the right). Being as I was driving 50-60 mph I thought that was a minor issue. :) Esp. since it (picture) was taken with an iPhone!
