Why Harlow Lake dries this way

Terrain & soil

Harlow Lake sits in the Marquette, MI area, on sandy soil that drains fast over terrain that drains at an even, moderate pace. Heavy tree cover holds the damp in, so it stays wet longer than the sky overhead would suggest. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour. The NE-facing aspect catches morning sun, so the surface firms up earlier in the day, and the gentle terrain, about a 4.2° average grade at 699 ft, drains slowly enough that low spots stay soft after a storm. Trails on the map here include Animoosh, Lake Superior and Ishpeming RR and Jedi.

How these factors affect drying

SoilSandy

Sandy, coarse soil sheds water fast. These trails are among the quickest to recover after rain.

CanopyDense 87%

Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.

TerrainModerate

Terrain here drains at a moderate pace. It neither sheds nor holds water strongly.
