Why Shell Ridge dries this way

Shell Ridge (Bay Area, CA) rides on loam soil that drains well over terrain that drains at an even, moderate pace. With little tree cover, sun and wind get to the dirt fast. 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 144 ft, Shell Ridge rides SW-facing ground that gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture; the gentle grade, around 3.5° on average, drains slowly enough that low spots stay soft after a storm. Savannah Trail, Forgotten Trail and Cottonwood Trail are among the named trails our map data covers here.
