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 77%

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.
