How we check ourselves

How these factors affect drying

SoilLoam

Loam balances drainage with water retention, so it typically takes a day or two to dry after meaningful rain.

CanopyDense 84%

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.
