Why Chino Hills State Park dries this way

Chino Hills State Park (Orange County & Inland Empire, CA) rides 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. 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 1,047 ft, Chino Hills State Park rides ENE-facing ground that catches morning sun, so the surface firms up earlier in the day; the gentle grade, around 4.4° on average, drains slowly enough that low spots stay soft after a storm.
