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.
CanopyDense 71%
Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.
TerrainHolds water
Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
