Is Joaquin Miller rideable today?

Yes. The live verdict is DUSTY: rideable, but very dry and loose over hardpack. No measurable rain in the past week.

Soil and terrain at Joaquin Miller

Joaquin Miller is a mountain bike trail network in Bay Area, CA. Soil data at the sampled location is classified as loam. Dense tree cover can reduce sun and wind exposure, slowing drying. Terrain data indicates an elevation of about 1,293 ft, an average terrain slope of 9° and a predominant SW-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Trails here include Sunset Loop and Sinawik Loop. 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 we check ourselves

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.

CanopyDense 65%

Dense tree cover can reduce sunlight and wind at ground level, slowing drying. Its effect depends on weather and local openings.

TerrainSteep

Steeper terrain can encourage runoff. Terrain slope does not measure the trail tread or its drainage features.
