They're all about 45 minutes from Mt. Hood Meadows, Timberline, Cooper Spur and Ski Bowl. They're also about 45 minutes from places on the Oregon Coast you can go surfing in the summer, though I always opted to go wakeboarding on the Willamette.
You're about 3 hours from all the places near Seattle, and about 3 hours from Mt. Bachelor.
I went to Gonzaga in Spokane, WA and it's close to 49 degrees North, Mt. Spokane, Silver Mountain, Lookout Pass, and Schweitzer.
Mt. Hood is better than all the places over here in eastern WA and north Idaho.
In the Northwest there are tons of places to go though. Crystal, Mt. Hood, Mt. Baker, Steven's Pass, etc. If you go to college anywhere near Portland or Seattle you won't be more than an hour from plenty of good skiing.
