Why Montara Mountain dries this way

Terrain & soil

Montara Mountain sits in the Bay Area, CA area, on gravelly sandy soil that drains fast over terrain that sheds water and dries quickly. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour. The WSW-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture, and the steep terrain, about a 12.7° average grade at 502 ft, sheds water fast once the rain stops. Old San Pedro Mountain Road, Historic "Old Colma Rd" (1879-1915) AKA Devil's Slide and Gray Whale Cove Trail are among the named trails our map data covers here.

How these factors affect drying

SoilGravelly sandy

About 19% of this ground is rock fragments, so water runs through it faster than the soil type alone suggests. It dries quicker than plain sandy.

CanopyPartial 45%

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.

Loam models conditions for Montara Mountain as a whole, so the verdict on this page covers the network rather than scoring each trail separately.

What's the terrain and elevation like at Montara Mountain?

Montara Mountain sits at roughly 502 feet, faces mostly WSW, and averages a 12.7° grade with about 45% tree cover. That makes it an afternoon-sun network where mornings run tackier, and the steep grade means it sheds water quickly. Loam models this exact ground against live weather rather than using one regional forecast.
