Why Millersylvania State Park dries this way
Terrain & soilMillersylvania State Park sits in the Seattle & Snoqualmie, WA 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 terrain here is nearly flat (a 1.5° average grade at 210 ft) and lets water sit, so the flat stretches are the last to firm up, while the SSE-facing aspect soaks up sun through the middle of the day, which speeds drying and opens the season earlier.

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 71%
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.
