Soil and terrain at Duthie Hill

Duthie Hill is a mountain bike trail network in Seattle & Snoqualmie, WA. The soil is gravelly sandy and drains fast. Heavy tree cover can slow drying after rain. The terrain averages a 0.2° slope at 551 ft and mainly faces N. Its nearly flat slopes can hold water in flat stretches.

How these factors affect drying

SoilGravelly sandy

About 20% of this ground is rock fragments, so water runs through it faster than the soil type alone suggests. It dries quicker than plain sandy. The soil type here is classified, but the exact drying speed is modeled from that classification rather than measured directly at this spot.

CanopyDense 79%

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.
