Why Lynch Canyon Open Space dries this way

Lynch Canyon Open Space is a mountain bike network in the Bay Area region of CA, riding on clay soil that holds water over terrain that drains at an even, moderate pace. With little tree cover, sun and wind get to the dirt fast. What really sets the timing here is how quickly that ground gives back a firm, dry surface, not what the day’s forecast says. At 840 ft, Lynch Canyon Open Space rides E-facing ground that catches morning sun, so the surface firms up earlier in the day; the rolling grade, around 5.7° on average, drains steadily rather than pooling.
