Soil and terrain at Waterfall Glen Forest Preserve

Waterfall Glen Forest Preserve is a mountain bike trail network in Chicago, IL. Soil data at the sampled location is classified as clay. Dense tree cover can reduce sun and wind exposure, slowing drying. Terrain data indicates an elevation of about 682 ft, an average terrain slope of 0.8° and a predominant E-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

SoilClay

Clay can retain moisture and become slick when wet. Wait for a firm trail surface and respect posted closures. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyDense 78%

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

TerrainGentle

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