Why Lambton County Heritage Forest dries this way

Terrain & soil

Lambton County Heritage Forest is a mountain bike network in the London & Sarnia region of ON, Canada, riding on loam soil that drains well over terrain that holds water and dries slowly. Heavy tree cover holds the damp in, so it stays wet longer than the sky overhead would suggest. What really sets the timing here is how quickly that ground gives back a firm, dry surface, not what the day’s forecast says. The N-facing aspect keeps the dirt shaded for much of the day, so moisture lingers after rain and snow is slow to clear, and the nearly flat terrain, about a 0.8° average grade at 607 ft, 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.

CanopyDense 100%

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

TerrainHolds water

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