Mountain bike trail conditions · Marquette, MI
Trails are dry, excuses aren't.
Harlow Lake (Marquette, MI) pairs fast-draining soil with flat, forested terrain. Loam reads that profile against live weather to call conditions here instead of guessing from a regional forecast.
Harlow Lake’s drying behavior comes down to what Loam measures for this exact location:
Sandy and coarse-grained soils shed water quickly — excess moisture drains down through the soil profile rather than pooling on the surface. Trails on fast-draining soil can recover within hours of light rain, making them some of the most resilient riding around.
Heavy tree cover shields trails from sun and wind, slowing evaporation after rain. Forested trails stay shaded and cool — great in summer heat, but they take longer to dry than open terrain, and drip from leaves can keep things damp even after dry days.
Flat trails have nowhere for water to go. Low spots and natural depressions collect standing water and mud that lingers well after the rain stops, so these networks often stay wet longer than the weather alone suggests.
Slopes here are predominantly southwest-facing, with about 2% rock fragment content in the soil — a factor in how fast the surface sheds water and dries.

As of the latest update, Harlow Lake is Rideable now (PRIME). Trails are dry, excuses aren't. 0.7″ of rain, 6d ago.
Harlow Lake sits on fast-draining ground (Sandy / coarse soil). Sandy and coarse-grained soils shed water quickly — excess moisture drains down through the soil profile rather than pooling on the surface. Trails on fast-draining soil can recover within hours of light rain, making them some of the most resilient riding around.
On its fast-draining soil, Harlow Lake typically takes only a few hours to recover after light rain, and its flat terrain can hold water longer in low spots. Heavy tree cover slows drying further.
Yes — Harlow Lake is in a northeast snow climate, so winter riding can be limited by snowpack or freeze-thaw. Loam flags a FROZEN state when the ground is snow-covered or frozen.
