Why Wissahickon Valley Park dries this way

Terrain & soil

Wissahickon Valley Park sits in the Philadelphia, PA area, 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. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour. The SSW-facing aspect soaks up sun through the middle of the day, which speeds drying and opens the season earlier, and the gentle terrain, about a 2.1° average grade at 253 ft, drains slowly enough that low spots stay soft after a storm.

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 96%

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.
