Soil and terrain at Cowiche Canyon

Cowiche Canyon is a mountain bike trail network in Seattle & Snoqualmie, WA. Soil data at the sampled location is classified as loam. Terrain data indicates an elevation of about 1,326 ft, an average terrain slope of 0.5° and a predominant NNE-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.

CanopyPartial 40%

Partial tree cover suggests a mix of sun and shade. Local exposure and surface conditions can vary across the network.

TerrainGentle

Gentle terrain can allow water to linger, but slope alone does not establish whether water pools on a trail.
