Soil and terrain at Harbison State Forest

Harbison State Forest is a mountain bike trail network in South Carolina. Soil data at the sampled location is classified as clay. Dense tree cover can reduce sun and wind exposure, slowing drying. Terrain data indicates an elevation of about 223 ft, an average terrain slope of 2.7° and a predominant NE-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Loam models conditions across the network; individual trails and constructed surfaces can differ from these environmental inputs. Official closures and conditions on the ground take priority.

How we check ourselves

How these factors affect drying

SoilClay

Clay can retain moisture and become slick when wet. Wait for a firm trail surface and respect posted closures. Drying behavior is modeled from the soil classification, not measured directly on the trail.

CanopyDense 90%

Dense tree cover can reduce sunlight and wind at ground level, slowing drying. Its effect depends on weather and local openings.

TerrainGentle

Gentle terrain can allow water to linger, but slope alone does not establish whether water pools on a trail.
