Ascent Trip Report

We decided to try to ski up Mount Catherine by a novel route suggested by Martin Volken's 2002 guidebook "Backcountry Skiing Snoqualmie Pass"--up from the north, instead of the usual approach from Windy Pass. This worked out well for us, saving a long boring road ski and allowing us to bonus-bag Mount Hyak on the way out. See the GPS track for our route.

The north and northwest slopes of Catherine are quite steep and forested, and the ski-bushwhacking can be challenging. We used many slopes of the Summit East (Hyak) ski area, which were a bit crowded with downhillers in the afternoon--as we skinned up we stayed to the edge of the downhill trails, and we saw numerous ski patrollers and no one accosted us as we skinned uphill. So we used a few groomed trails without every paying for anything.

The crux of our route on Catherine was a short, steep icy couloir, which we booted up and down with skis on our backs--on the downhill we only walked down about 40 vertical feet on the narrowest and iciest part. Other than that, this was a true skis-on-summit climb.

Other obstacles where huge logs we had to cross on snowdrifts, and a few narrow tree well spots in the lower logged-over section. Most of the old growth was good skiing, although the snow was icy crust with just a couple inches of powder--not the greatest, but at least one could make turns more easily than in the usual Cascade concrete.

The high point of Mount Hyak was a snow mound just north of the exit chute from the Hidden Valley chairlift.

All in all a successful and enjoyable outing. The skies were pretty overcast and it snowed lightly pretty much all day, but it certainly could have been far worse.
