Terrain & soilSummit Bike Park sits in the Seattle & Snoqualmie, WA area, 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. 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 E-facing aspect catches morning sun, so the surface firms up earlier in the day, and the rolling terrain, about a 9.1° average grade at 2,933 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 76%
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.
