Soil and terrain at Antelope Island

Antelope Island is a mountain bike trail network in Salt Lake City, UT. The soil is rocky sandy and drains fast. With little tree cover, the ground gets plenty of sun and wind. The terrain averages a 9.5° slope at 4,856 ft and mainly faces NW. Its rolling slopes drain steadily.

How these factors affect drying

SoilRocky sandy

About 46% 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.

CanopyOpen 0%

Little tree cover means full sun and wind, so these trails are among the fastest to rebound after rain.

TerrainSheds water

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