No measurable rain in the window. Over the tracked history, Crystal Mountain (WA) has been rideable on 10 of the last 10 days. Daily trail markers are representative daytime outlooks. Weather is one input. The rideability verdict also accounts for soil, terrain, canopy, and drying time.

Why Crystal Mountain (WA) dries this way

Crystal Mountain (WA) sits in the Seattle & Snoqualmie, WA area, on sandy soil that drains fast over terrain that sheds water and dries quickly. 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 steep terrain, about a 21.8° average grade at 4,807 ft, sheds water fast once the rain stops.
