Soil and terrain at Swasey Recreation Area

Swasey Recreation Area is a mountain bike trail network in California. Soil data at the sampled location is classified as sandy. Terrain data indicates an elevation of about 1,621 ft, an average terrain slope of 5.8° and a predominant SE-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

SoilSandy

Sandy soil generally allows water to drain readily. Rainfall, shade and trail construction also affect recovery. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyPartial 30%

Partial tree cover suggests a mix of sun and shade. Local exposure and surface conditions can vary across the network.

TerrainModerate

Moderate terrain slope is one input to the drying model. Local drainage also depends on soil and trail construction.
