When does Chinook Pass / Crystal Mountain close?
Closure risk
High
Typical window
Any time
Typical reopen
~2 hr
Closures here aren't limited to a fixed morning window — they can happen at any time of day during an active storm, usually reopening about roughly 2 hours after control work wraps up.
In StormDrop's closure model, risk starts building once a storm cycle pushes past about 12" of new snow and climbs steeply above roughly 24". Sustained wind above about 25 mph adds risk through blowing and drifting snow.
Traction-law restrictions tend to appear well before a full closure — often around 6" of fresh accumulation — so carrying chains or running AWD/4WD with snow tires is the safe default on a storm day.
These are StormDrop's closure-model tendencies and general corridor knowledge — not a published schedule or a guarantee. WSDOT makes the real-time call. Always confirm live SR-410 status before you go.
Beating the closure
Closures here aren't tied to a set time — build slack into your plan and watch live status all morning.
Carry chains or run AWD/4WD with dedicated snow tires whenever a storm is in the forecast — a traction law can go up before the road ever closes.
Check the live WSDOT status above before you leave, and again mid-drive — storm-day conditions on SR-410 can flip within minutes.
Have a backup resort or a later-start plan so a control-work delay doesn't cost you the day.
