Soil and terrain at Montara Mountain

Montara Mountain is a mountain bike trail network in Bay Area, CA. Soil data at the sampled location is classified as gravelly sandy. Terrain data indicates an elevation of about 502 ft, an average terrain slope of 12.7° and a predominant WSW-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Trails here include Old San Pedro Mountain Road, Historic "Old Colma Rd" (1879-1915) AKA Devil's Slide and Gray Whale Cove Trail. 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

SoilGravelly sandy

The soil data includes about 19% rock fragments. The model uses this to adjust drainage; it does not measure how quickly every trail section dries. Drying behavior is modeled from the soil classification, not measured directly on the trail.

CanopyPartial 45%

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

TerrainSteep

Steeper terrain can encourage runoff. Terrain slope does not measure the trail tread or its drainage features.
