Why Topanga State Park dries this way

Topanga State Park sits in the Orange County & Inland Empire, CA area, on gravelly loam soil that drains fast over terrain that drains at an even, moderate pace. 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. At 1,703 ft, Topanga State Park rides SSW-facing ground that soaks up sun through the middle of the day, which speeds drying and opens the season earlier; the rolling grade, around 6° on average, drains steadily rather than pooling.
