Soil and terrain at Tilden

Tilden is a mountain bike trail network in Bay Area, CA. Soil data at the sampled location is classified as loam. Terrain data indicates an elevation of about 1,230 ft, an average terrain slope of 7.4° and a predominant WSW-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Trails here include Quarry Path, Big Springs Trail and Wildcat Gorge 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 these factors affect drying

SoilLoam

Loam combines drainage with water retention. Soil type alone does not establish how long this network takes to dry. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyPartial 50%

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.
