Followed the instructions from this geology blog post to go look for fossils above Racehorse Creek.
Access. The N Fk Rd had a generous amount of potholes. The fork of the road that climbs up to the trailhead (missing from Google Maps!) on the other hand was in good condition.
Conditions. The decommissioned road section of the trail had ditches to climb in/out every hundred feet or so, but no other obstacles. No issues with the narrow trail through the forest. The final, steep section to the top of the ridge had some ropes installed, but the dirt was just moist enough to provide good footing.
Wildlife. Plentiful fossilized leafs, even at the bottom of the steep section. Almost every rock you picked up had some traces of a fossil, but for best results you'd need to bring tools for splitting rock.
Crowds. Encountered two parties.
