Soil and terrain at Summit Bike Park

Summit Bike Park is a mountain bike trail network in Seattle & Snoqualmie, WA. Soil data at the sampled location is classified as sandy. Sandy soil can help drainage, while dense tree cover can slow drying by reducing sun and wind exposure. Terrain data indicates an elevation of about 3,215 ft, an average terrain slope of 14.2° and a predominant ENE-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Loam models conditions across the network; individual trails and constructed surfaces can differ from these environmental inputs. Official closures and conditions on the ground take priority.

How these factors affect drying

SoilSandy

Sandy soil generally allows water to drain readily. Rainfall, shade and trail construction also affect recovery. Drying behavior is modeled from the soil classification, not measured directly on the trail.

CanopyDense 77%

Dense tree cover can reduce sunlight and wind at ground level, slowing drying. Its effect depends on weather and local openings.

TerrainSteep

Steeper terrain can encourage runoff. Terrain slope does not measure the trail tread or its drainage features.
