Soil and terrain at Lake Whatcom

Lake Whatcom is a mountain bike trail network in Bellingham, WA. Soil data at the sampled location is classified as loam. Dense tree cover can reduce sun and wind exposure, slowing drying. Terrain data indicates an elevation of about 1,437 ft, an average terrain slope of 21.5° and a predominant WSW-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

SoilLoam

Loam combines drainage with water retention. Soil type alone does not establish how long this network takes to dry. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyDense 82%

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.
