Whetstone Mountain is usually climbed as a short side hike from the Silver King Mountain trail in the Bull of the Woods Wilderness (Clackamas River headwaters). It is the highest point on a ridgeline that separates the Clackamas drainage from the headwaters of the Little North Santiam River. When I posted a query on the Portland hiking forum, no one had ever tried the hike from the south, but many people responded saying they had done the side hike and that the hike was gorgeous. That was enough for us to give it a shot.
We hiked from the Opal Creek trailhead about a half mile before turning uphill, and climbed steeply (~800 fpm) for about three miles. It was an adventure from the get-go, as it became clear that the trail had received no maintenance for quite some time. Deadfalls and blowdown covered the trail and constantly required scrambling over and ducking under logs.
We finally reached the ridgetop, and immediately noticed two things: One, a spectacular view of Mt Hood
And two, a LOT of snow on the ground. In fact, it was virtually impossible to find the trail.
We eventually just headed up the ridgeline as best we could, stumbling randomly upon the trail as the south face of the ridge became more exposed. We made the decision to push for the summit, even though the day was getting late. We hit heavy snow again a couple hundred feet from the top, which slowed our progress and made for some tense spots. The view at the top absolutely blew us away. 360 degree view of the major peaks of the cascades.

The beargrass and rhododendron blooms were gorgeous in the evening light as we head back down the trail.
All in all, a fantastic adventure, with a payoff of incredible views.
