Wednesday, October 21st at 6pm
Rain moved in. Verdict dropped to STAY OFF.

Soil and terrain at Bonelli Regional Park

Bonelli Regional Park is a mountain bike trail network in Orange County & Inland Empire, CA. 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 1,165 ft, an average terrain slope of 1.8° and a predominant NNE-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

SoilLoam

Loam combines drainage with water retention. Soil type alone does not establish how long this network takes to dry. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyOpen 11%

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

TerrainGentle

Gentle terrain can allow water to linger, but slope alone does not establish whether water pools on a trail.
