The preserve is home to many prehistoric sandstone formations, including the Peachtree Rock pictured here. The formations originated millions of years ago, when oceans washed over the area leaving behind marine fossils, sand, and intertidal deposits.

The rock’s unique shape is a result of the softer sandstone on the bottom eroding at a much faster rate than the the upper section, which is strengthened by a layer of ironstone.

The preserve also harbors the Midlands’ only naturally-occurring waterfall!
