Soil and terrain at Banner Forest

Banner Forest is a mountain bike trail network in Seattle & Snoqualmie, WA. The soil here is organic. Heavy tree cover can slow drying after rain. The terrain averages a 1.5° slope at 433 ft and mainly faces NW. Its nearly flat slopes can hold water in flat stretches.

How these factors affect drying

SoilOrganic soil

The soil survey describes organic material at this spot, not a mineral soil texture. The drying model uses surveyed water-retention values. Organic soils vary in how they drain, so this label alone does not tell you how quickly the trail will dry.

CanopyDense 81%

Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.

TerrainHolds water

Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
