How we check ourselves

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.

CanopyOpen 5%

Little tree cover means full sun and wind, so these trails are among the fastest to rebound after rain.

TerrainHolds water

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