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 steep (a 13.9° average grade at 2,015 ft) and sheds water fast once the rain stops, 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 81%
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.

Does Tiger Mountain get snow in winter?
Yes. At 2,015 ft, Tiger Mountain typically sees winter snow and freeze-thaw that can pause riding. Loam flags a FROZEN state when the ground is snow-covered or frozen, then clears it as things thaw and dry.
What's the terrain and elevation like at Tiger Mountain?
Tiger Mountain sits at roughly 2,015 feet, faces mostly S, and averages a 13.9° grade with about 81% tree cover. That makes it a sunny, fast-drying network, and the steep grade means it sheds water quickly. 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 2,015 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.
