Geology
The cave is entered via a steel ladder through a collapsed roof section. The most notable features of the cave are its two hornito skylights in the eastern passage, for which the cave is named. During the cave's formation, it may have had more hornitos suggested by the many small cupolas along its passage. The entrance may have been a hornito that collapsed. The eastern passage has mostly original morphology, but the western passage is filled with sand and clay and some piles of breakdown. The western passage is longer and more difficult to navigate.

History
Skylight Cave is closed during the late fall to early spring periods because of hibernating Townsend's big-eared bats.. Many years worth of rotted ladders were once strewn around the entrance floor.
