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.

CanopyDense 77%

Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.

TerrainSheds water

Water runs off this terrain rather than pooling, which helps the surface dry out after rain.
