Why Swan Creek Park dries this way

Terrain & soil

Swan Creek Park sits in the Seattle & Snoqualmie, WA area, on gravelly sandy soil that drains fast over terrain that drains at an even, moderate pace. 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 NNE-facing aspect keeps the dirt shaded for much of the day, so moisture lingers after rain and snow is slow to clear, and the gentle terrain, about a 3.6° average grade at 328 ft, drains slowly enough that low spots stay soft after a storm.
