Soil and terrain at South Mountain Park & Preserve

South Mountain Park & Preserve is a mountain bike trail network in Phoenix & Scottsdale, AZ. 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 1,381 ft, an average terrain slope of 11.8° and a predominant NW-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 16% 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.

TerrainSteep

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