Why Trexler Nature Preserve dries this way

Terrain & soil

Trexler Nature Preserve (Lehigh Valley, PA) rides on loam soil that drains well over terrain that holds water and dries slowly. Heavy tree cover holds the damp in, so it stays wet longer than the sky overhead would suggest. Loam reads that exact ground against live weather, rather than leaning on a regional forecast that can’t tell you what the dirt is doing. The terrain here is gentle (a 2.3° average grade at 453 ft) and drains slowly enough that low spots stay soft after a storm, while the WNW-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture.

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 74%

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.
