Terrain data indicates an elevation of about 7,064 ft, an average terrain slope of 6.7° and a predominant N-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

SoilGravelly sandy

The soil data includes about 29% 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.

CanopyPartial 43%

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

TerrainModerate

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