Soil and terrain at Riley Trails

Riley Trails is a mountain bike trail network in Grand Rapids, MI. Soil data at the sampled location is classified as sandy. Sandy soil can help drainage, while dense tree cover can slow drying by reducing sun and wind exposure. Terrain data indicates an elevation of about 650 ft, an average terrain slope of 0.2° and a predominant SW-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

SoilSandy

Sandy soil generally allows water to drain readily. Rainfall, shade and trail construction also affect recovery. The model uses surveyed water-retention values, not measured trail recovery times.

CanopyDense 83%

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.
