Soil and terrain at Lower Rock Creek

Lower Rock Creek is a mountain bike trail network in California. Soil data at the sampled location is classified as loam. Terrain data indicates an elevation of about 5,971 ft, an average terrain slope of 6.3° 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

SoilLoam

Loam combines drainage with water retention. Soil type alone does not establish how long this network takes to dry. Drying behavior is modeled from the soil classification, not measured directly on the trail.

CanopyPartial 38%

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.
