The Purgatory Chasm is decorated with plant life due to the abundance of water in the area. This flora can be found on the forest floor and in some of the cracks of the rock walls and depressions. This spot is also known for having tight canyon walls on either side of the trail in places. While there used to be a western trail looping back to the parking area from here, recently flooding and fallen trees have covered the area, making an out-and-back route more suitable.
