Soil and terrain at Spirit Mountain

Spirit Mountain is a mountain bike trail network in Duluth, MN. The soil is gravelly sandy and drains fast. Heavy tree cover can slow drying after rain. The terrain averages a 7.4° slope at 755 ft and mainly faces ESE. Its rolling slopes drain steadily. Trails here include Waabizheshikana: The Marten Trail, Beam Me Up Scotty and All-Weather Trail.

How these factors affect drying

SoilGravelly sandy

About 24% 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 70%

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

TerrainSheds water

Water runs off this terrain rather than pooling, which helps the surface dry out after rain.
