Why Castlewood State Park dries this way
Terrain & soilCastlewood State Park is a mountain bike network in the St. Louis region of MO, riding 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. What really sets the timing here is how quickly that ground gives back a firm, dry surface, not what the day’s forecast says. The terrain here is nearly flat (a 1.1° average grade at 440 ft) and lets water sit, so the flat stretches are the last to firm up, while the NW-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 83%
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.
