How we check ourselves

How these factors affect drying

SoilGravelly loam

About 24% of this ground is rock fragments, so water runs through it faster than the soil type alone suggests. It dries quicker than plain loam.

CanopyOpen 0%

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.
