Here's an idea that is probably bad or at least ill-thought out: could we take some of the pressure off of Mount Bachelor by creating a small, community ski area on Tumalo? There could be a fixed-grip double or triple going to the summit from the road servicing 1,400' of SW facing terrain, and then maybe a Poma lift/t-bar dropping off the top into the E facing bowl servicing 500' of expert terrain. Other than the lifts you would need to cut some ski trails on the SW slopes and perhaps do a bit of tree-thinning for glades and create a larger parking area, but on the whole the infrastructure requirements would be pretty minimal. The place could offer some pretty neat skiing for locals but wouldn't be a draw for tourists - you get way more vertical, acreage, amenities, and the ability to use your Ikon Pass at Bachelor.
Realistically, getting financing and forest service approval (it is outside of federal wilderness) for such a project would be very challenging. The biggest hurdle in generating support would likely be opposition from backcountry skiers. There aren't that many places to backcountry ski in the area unless you like long approaches or have a sled, so the idea of developing Tumalo, even if the development is kept minimal, kind of stinks? One way to mitigate this problem would be to allow free uphill access.
If we're really talking pie in the sky types of ideas, we could pair a Tumalo community ski area with expanded backcountry skiing access. What I'm about to propose might cost just as much or more than creating a Tumalo ski area, but imagine if NF 370/380 (once again, all outside of federal wilderness) were improved and kept plowed in the winter? Those roads are in rough shape and get a ton of snow, but there isn't very much avalanche danger if any on the way to the Broken Top trail. Being able to start a tour at that trailhead would create some pretty amazing touring options. There are cool terrain options there, with everything from hard-charging lines to a surprising amount of mellow, non-avalanche terrain that could be fun for beginners or high-danger days.
Anyway, none of the above is serious but these thoughts crossed my mind last season while skiing at Bachelor.
