Due to the rarity of resources and the difficulty of this hike, park rangers don't actively encourage use of this trail, but for the conservation-minded, it can be an exceptional experience. The world's largest concentration of standing petrified trees can be found on this ridge in the park's northeast region, to the southwest of the Lamar Valley. There are also plenty of unusual fossils, such as impressions of leaves left behind on rocks. Access is via a difficult but
rewarding 3.2-mile (one-way) hike.
