Why Swan Creek Park dries this way
Terrain & soilSwan Creek Park sits in the Seattle & Snoqualmie, WA area, on gravelly sandy soil that drains fast 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 NW-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture, and the nearly flat terrain, about a 1.3° average grade at 436 ft, lets water sit, so the flat stretches are the last to firm up.

How these factors affect drying
SoilGravelly sandy
About 20% of this ground is rock fragments, so water runs through it faster than the soil type alone suggests. It dries quicker than plain sandy.
CanopyDense 73%
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.
