Endless. Starting from the summit of Mt St Helens.

Mt Hood. Accessibility is almost always guaranteed. As long as you can get parking. Push for the summit, or just do laps to the top of the Palmer ski lift (there is a well marked “climbers trail” that the snow cats make).

Mt St Helens. Yes, we know the mountain is in Washington, but it’s so close to Portland it has to be on the list. Similar to Mt Hood, the snowparks of Washington are reliably accessible (Marble Mountain). Make sure you buy a SnowPark Pass before you’re there, usually poor cell phone reception at the snowparks. Once there’s a decent snowpack, it can be one amazing descent from the summit to the parking lot.

Bend. If Mt Bachelor isn’t calling your name, there’s a number of areas that offer shorter slopes within 30 minutes of Bend, or make a push for South Sister (either a very long approach, you can pay for a shuttle from a snowmobile). Broken Top is also in the vicinity.

Wallowing in deep snow.
