Soil and terrain at Grey Butte / Skull Hollow
Grey Butte / Skull Hollow is a mountain bike trail network in Bend, OR. Soil data at the sampled location is classified as loam. Open tree cover can allow more sun and wind exposure, helping drying. Terrain data indicates an elevation of about 3,445 ft, an average terrain slope of 3.4° and a predominant NE-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Trails here include Gray Butte Trail, Ridge Rider - Cole Loop and Cole Loop Trail. 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 these factors affect drying
SoilLoam

CanopyOpen 17%
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.
