Why Tamarancho dries this way

Terrain & soil

Tamarancho (Bay Area, CA) rides on loam soil that drains well over terrain that sheds water and dries quickly. Loam reads that exact ground against live weather, rather than leaning on a regional forecast that can’t tell you what the dirt is doing. At 764 ft, Tamarancho rides WNW-facing ground that gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture; the rolling grade, around 10° on average, drains steadily rather than pooling. Trails on the map here include Miwok Trail, Dias Ridge Trail and Camino del Canon.

CanopyPartial 27%

A mix of sun and shade. Conditions vary across the network, with open sections drying faster than covered ones.

TerrainSheds water

Water runs off this terrain rather than pooling, which helps the surface dry out after rain.
