Soil and terrain at Bald Mountain

Bald Mountain is a mountain bike trail network in Boise, ID. Soil data at the sampled location is classified as rocky loam. Terrain data indicates an elevation of about 5,791 ft, an average terrain slope of 15.8° and a predominant NE-facing aspect. Terrain slope does not measure the trail tread or its drainage features. 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

SoilRocky loam

The soil data includes about 42% rock fragments. The model uses this to adjust drainage; it does not measure how quickly every trail section dries. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyPartial 47%

Partial tree cover suggests a mix of sun and shade. Local exposure and surface conditions can vary across the network.

TerrainSteep

Steeper terrain can encourage runoff. Terrain slope does not measure the trail tread or its drainage features.
