Why Sunol Regional Wilderness dries this way

Sunol Regional Wilderness (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 1,089 ft, Sunol Regional Wilderness rides W-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.
