Why Guajome Regional Park dries this way

Guajome Regional Park sits in the Orange County & Inland Empire, CA area, on clay soil that holds water over terrain that holds water and dries slowly. 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 terrain here is nearly flat (a 0.4° average grade at 108 ft) and lets water sit, so the flat stretches are the last to firm up, while the ENE-facing aspect catches morning sun, so the surface firms up earlier in the day.

How these factors affect drying

SoilClay

Dense clay holds moisture and stays slick the longest. It needs the most drying time before it’s worth riding. The soil type here is classified, but the exact drying speed is modeled from that classification rather than measured directly at this spot.

CanopyPartial 41%

A mix of sun and shade. Conditions vary across the network, with open sections drying faster than covered ones.

TerrainHolds water

Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
