Soil and terrain at South Trails

South Trails is a mountain bike trail network in Marquette, MI. Soil data at the sampled location is classified as gravelly 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 1,109 ft, an average terrain slope of 3.2° and a predominant NNE-facing aspect. Terrain slope does not measure the trail tread or its drainage features. Trails here include Carp Eh Diem, Rough Rock Ridge and Greywalls. 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

SoilGravelly sandy

The soil data includes about 23% rock fragments. The model uses this to adjust drainage; it does not measure how quickly every trail section dries. Drying behavior is modeled from the soil classification, not measured directly on the trail.

CanopyDense 85%

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.

FAQ

The soil data at the sampled location is classified as gravelly sandy. This describes an environmental input, not a survey of every trail surface.

How long does South Trails take to dry after rain?

South Trails has no fixed drying time. Rainfall, soil moisture, shade and the weather that follows all matter. Check the current estimate and wait until the trail surface is firm.

Can you ride South Trails after rain?

Sandy soil can help drainage, but heavier rain, shade and the trail surface also affect recovery. Wait until the surface is firm. Check the current estimate before heading out, and turn back if your tires leave ruts.

What does a frozen condition mean at South Trails?
