How we check ourselves

How these factors affect drying

SoilOrganic soil

The soil survey describes organic material at this spot, not a mineral soil texture. The drying model uses surveyed water-retention values. Organic soils vary in how they drain, so this label alone does not tell you how quickly the trail will dry.

CanopyOpen 11%

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.
