I have tried making it to the Highway 14 pinnacles (Bighorn Mountains, WY) earlier this summer but a ghetto truck made getting to the towers unfeasible. Bridget and I finally made it this past weekend, but we barely made it out of the area.
We arrived at the Coyote rocks area in the evening with pent-up energy from the drive. We immediatly free-soloed the "trickster" pinnacle (5.6) and sucked in the view of the area; what a setting! We were at timberline, there was a snowfield near by, and there were hundreds of domestic sheep grazing around us and the towers.
We ended up climbing most of the towers in between rain storms.
The highway 14 pinnacles were really fun to climb at but it was adventure climbing. There was alot of loose rock and the leading was pretty heady (i.e. don't bring alot of gear because you won't place it). We almost got stuck there as well. The description of the area states not to drive on the 4x4 road when it rains. We decided it was no big deal to drive out once we climbed most of the towers so we headed down the rutted road. It turned out the road turnes to gumbo mud when wet and getting out of there was the most gripping part of the trip; but we managed to make it out with out destroying the truck.
We then headed to drier places (Tensleep) to go sport climbing. I have never been to Tensleep before so it was time to drink the cool-aid. I found the stone to be awesome, the climbing pumpy, and routes bolted liberally. It was stellar!
