Soil and terrain at Harbison State Forest

Harbison State Forest is a mountain bike trail network in South Carolina. The soil is clay and holds water. Heavy tree cover can slow drying after rain. The terrain averages a 2.7° slope at 223 ft and mainly faces NE. Its gentle slopes drain slowly, so low spots can stay soft after rain.

How these factors affect drying

SoilClay

Dense clay holds moisture and stays slick the longest. It needs the most drying time before it’s worth riding.

CanopyDense 90%

Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.

TerrainHolds water

Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
