Terrain & soilDuthie Hill is a mountain bike network in the Seattle & Snoqualmie region of WA, riding on sandy soil that drains fast over terrain that sheds water and dries quickly. 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 WSW-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture, and the rolling terrain, about a 11.4° average grade at 361 ft, drains steadily rather than pooling.

How these factors affect drying
SoilSandy
Sandy, coarse soil sheds water fast. These trails are among the quickest to recover after rain.
CanopyDense 81%
Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.
TerrainSheds water
Water runs off this terrain rather than pooling, which helps the surface dry out after rain.
