Why Stimpson Family Nature Reserve dries this way

Terrain & soil

Stimpson Family Nature Reserve sits in the Bellingham, WA area, on loam soil that drains well 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 W-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture, and the gentle terrain, about a 3.6° average grade at 1,322 ft, drains slowly enough that low spots stay soft after a storm.
