The total elevation change of the gorge trail is 1035 feet. The rock wall is about 380 million years old. The rocks in Enfield Glen (the Treman Gorge) are shale and sandstone formed in the Late Devonian era. The alternating layers represent repeated shifts in sea level, and make for excellent fossil-hunting. The straight lines in the gorge are cracks that geologists refer to as joint lines. Many of the joint lines were formed from natural gas that vented up and out of the rocks many millions of years ago. They overlap throughout the region at near right angles giving the rocks a "quarried" look.
