Over the tracked history, Crystal Mountain (WA) has been rideable on 10 of the last 10 days. Loam also considers soil, slope, tree cover, and drying time.

Soil and terrain at Crystal Mountain (WA)

Crystal Mountain (WA) 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 4,807 ft, an average terrain slope of 21.8° and a predominant W-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 we check ourselves

How these factors affect drying

SoilSandy

Sandy soil generally allows water to drain readily. Rainfall, shade and trail construction also affect recovery. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyDense 76%

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.
