Soil and terrain at Illiniwek Forest Preserve

Illiniwek Forest Preserve is a mountain bike trail network in Illinois. Soil data at the sampled location is classified as loam. Dense tree cover can reduce sun and wind exposure, slowing drying. Terrain data indicates an elevation of about 650 ft, an average terrain slope of 3.4° 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

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.

CanopyDense 87%

Dense tree cover can reduce sunlight and wind at ground level, slowing drying. Its effect depends on weather and local openings.

TerrainModerate

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