Glendive Trip


PetrolPete

Recommended Posts

Since I just found out I won't have to work this weekend, I'm going to go on my first fossil hunt since August and will be taking a trip over to Glendive to hit a couple locations I've heard about. The first is an ammonite site in the bearpaw or pierre shale that was reccomended on the forum. The second is a public Hell Creek location that my friend told me about where I was going to look for plant material, since my friend says he has seen some impressions in the area. If anyone is in the area they are more than welcome to join in. Also, if anyone has any additional reccomendations for places to visit or maps to look over, I'm more than happy to hear your advice.

I'll post my finds here when I get a chance next week.

Thank you,

Peter

I ended up having to work Saturday and Monday, but I did get a chance to make it out there on Sunday. I started off the day going to the ammonite site listed on this old thread http://www.thefossilforum.com/index.php?/topic/23282-ahhhthe-hell-creek-formation/?hl=%2Bahhh....+%2Bthe+%2Bhell+%2Bcreek . I looked around for a while, but couldn't find any concretions, so, when I was about to head back to town, I decided to head southeast aloing the road where I saw a nice rock slide that looked like concretions from the road. I walked over to it and found that they were actually blocks of fairly unconsolidated sandstone, probably from the fox hills formation. Even though they were not the concretions I was looking for I decided to give them a tap with my hammer, only to find they were filled with huge leaf impressions and remains of chunks of cretaceous wood. So I grabbed a couple chunks and headed to Makoshika park. They had a few good fossils from the area in the visitor station so I got a better idea of what to look for.I asked to see a map of the BLM land in the area and they showed me that there are two sections south of town, one is a small offroad vehicle (dirtbikes, atvs and dune buggys) area, clearly marked on the road south of town, and the other following the road I had been on earlier. I also bought a book, Rockhounding Montana, which listed a couple areas nearby Glendive in the two sections of BLM land. From there I went through the park, it had some really nice sites and exposures of the Hell Creek formation, but I was a little dissapointed in the lack of educational markers showing things like places dinos were found, where the K-T boundary is (I really wanted to put my finger on and take a picture where the dinosaurs bit it), etc. It is a place I plan on going back to at some point to hike the trails. From the park I headed south again to the offroad area where the book said there were marine fossils in the Pierre shale. I got there and found the best outcrop of the Pierre Shale was on the East side of the road. I started walking around, but most of the concretions were already broken and picked over. If I hadn't been so tired at that point (or atleast had a small offroad vehicle) I would have gone further east where I bet it is less picked over. But in the end I found some partial ammonites, baculites, petrified wood and selenite crystals there.

Sorry for the rushed post, but it's been pretty busy this week. I'll try and post pictures when I get a chance. Also, if anyone has had experience with the [probably] Fox Hills formation leaves, any prep/stabilization tips would be greatly appreciated.

Thank you,

Peter

Here is the site where the leaves came from

I don't know if anyone has used the app Theodolite, but I've found it is good for recording a lot of information on a location pretty quick, here is a picture of an area I wanted to look around in, but didn't have a chance (all the info is recorded in the upper left corner)

You crammed a lot of coolness into one day off! Thanks for taking us along :)

I feel as you do about the K-T boundary; I've acquired several samples of it from around the world, and they never fail to inspire my imagination.

That 'river of blocks' is certainly an odd vision, and to think that that they are full of fossil leaves....coolness!

Here are some more pictures of the material in one of the leaf blocks

Selenite Crystals:

The inside of an ammo coated with crystals:

I'm not sure what this is, it kind of looks like a bryzoan:

Mold of something, any ideas:

And some more crystals

If anyone has any IDs of anything, please let me know. Any help is greatly appreciated. Also I can try to take better pictures on request.

Fossil trips are a lot of fun. Your pictures are great. It was nice to see all that familiar terrain again.
