Why Aldergrove Regional Park dries this way

Terrain & soil

Aldergrove Regional Park sits in the Metro Vancouver, BC, Canada area, on loam soil that drains well over terrain that holds water and dries slowly. With little tree cover, sun and wind get to the dirt fast. 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 SSW-facing aspect soaks up sun through the middle of the day, which speeds drying and opens the season earlier, and the nearly flat terrain, about a 1.4° average grade at 200 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.

CanopyOpen 10%

Little tree cover means full sun and wind, so these trails are among the fastest to rebound after rain.

TerrainHolds water

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