Soil and terrain at Captain Ahab/Amasa Back

Captain Ahab/Amasa Back is a mountain bike trail network in Moab, UT. Soil data at the sampled location is classified as gravelly sandy. Open tree cover can allow more sun and wind exposure, helping drying. Terrain data indicates an elevation of about 4,551 ft, an average terrain slope of 6.3° and a predominant ENE-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Trails here include Captain Ahab Trail, HyMasa Trail and Jackson. 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

SoilGravelly sandy

The soil data includes about 30% rock fragments. The model uses this to adjust drainage; it does not measure how quickly every trail section dries. Drying behavior is modeled from the soil classification, not measured directly on the trail.

CanopyOpen 0%

Open tree cover can allow more sunlight and wind to reach the ground. Terrain, weather and trail construction also affect drying.

TerrainModerate

Moderate terrain slope is one input to the drying model. Local drainage also depends on soil and trail construction.
