Nothing technical with climbing, but once you get down in the subway, it’s wet and mossey. We had a guy take one step, slide, then say “oh man, this is slippery, I bet you a Dollar somebody goes down in here.“ He then took another step, and both feet went flying out from underneath him and he head slapped the solid rock floor and was out cold.
I felt like he was taking the bet too seriously, but still paid him a dollar. Very cool hike, though. There were some in our group who walked right past the Fossilized Raptor tracks without even noticing them. So don’t do that.
