Soil and terrain at Guajome Regional Park

Guajome Regional Park is a mountain bike trail network in Orange County & Inland Empire, CA. Soil data at the sampled location is classified as clay. Terrain data indicates an elevation of about 108 ft, an average terrain slope of 0.4° and a predominant ENE-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 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.

CanopyPartial 41%

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

TerrainGentle

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