Why Tiger Mountain dries this way
Terrain & soilTiger Mountain is a mountain bike network in the Seattle & Snoqualmie region of WA, riding on loam soil that drains well 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. 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 terrain here is rolling (a 7.8° average grade at 2,385 ft) and drains steadily rather than pooling, while the S-facing aspect soaks up sun through the middle of the day, which speeds drying and opens the season earlier.

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 82%
Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.
TerrainSheds water
Water runs off this terrain rather than pooling, which helps the surface dry out after rain.

Tiger Mountain sits at roughly 2,385 feet, faces mostly S, and averages a 7.8° grade with about 82% tree cover. That makes it a sunny, fast-drying network, and the rolling grade means it drains at a steady clip. Loam models this exact ground against live weather rather than using one regional forecast.
When is the best time of year to ride Tiger Mountain?
The reliable season at Tiger Mountain runs late spring through fall: at around 2,385 feet it holds real winter snowpack, and freeze-thaw makes the shoulder seasons hit or miss. Its sunny aspect helps it come back fast after storms. Loam flags FROZEN days and posts a live verdict, so the calendar never has to be the tiebreaker.
