The unique environment at Warbler Woods offers the perfect habitat for wildlife and plants. The Pecan Gap formation underlies our land. In some places the marl is present at the surface. This is a soft rock with enough clay content to prevent the rock from being completely hardened and erosion resistant. However, it is competent enough to retain fossils. In most areas we have a few inches to a few feet of black clay, derived from the calcareous rock in the area. Many of the stones present at or near the surface are chert with a limestone veneer. These apparently have eroded from Edwards Limestone from the Edwards Plateau above the escarpment.
