Soil and terrain at Morgan Territory Regional Preserve

Morgan Territory Regional Preserve is a mountain bike trail network in Bay Area, CA. Soil data at the sampled location is classified as clay. Terrain data indicates an elevation of about 1,647 ft, an average terrain slope of 4.4° and a predominant SSW-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. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyPartial 34%

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.
