The 25-acre (10 ha) preserve protects Stay High Cave, which houses seven rare cave-dwelling invertebrate species, three of which are only known from the county's Sinking Creek Valley.

More common species, such as salamanders, crickets, harvestmen, spiders, crayfish, and bats, also live within the cave's streams, riparian mud banks, and drip pools.

[2] The significance of the preserve was discovered in 1994, when speleologist Dave Hubbard inventoried the cave in response to local concerns.

Access is strictly limited to activities related to data collection and monitoring.
