Why Olson Park dries this way

Terrain & soil

Olson Park (Detroit & Ann Arbor, MI) rides on loam soil that drains well over terrain that holds water and dries slowly. Loam reads that exact ground against live weather, rather than leaning on a regional forecast that can’t tell you what the dirt is doing. At 892 ft, Olson Park rides ENE-facing ground that catches morning sun, so the surface firms up earlier in the day; the nearly flat grade, around 0.8° on average, lets water sit, so the flat stretches are the last to firm up.

How these factors affect drying

SoilLoam

Loam balances drainage with water retention, so it typically takes a day or two to dry after meaningful rain.

CanopyPartial 33%

A mix of sun and shade. Conditions vary across the network, with open sections drying faster than covered ones.

TerrainHolds water

Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
