There's lots of different kinds of forest in Oregon: old, young, lush, scraggly. The forest on this short hike in the Clackamas Foothills is best described as pretty. Only a square mile in area, surrounded by several logging tracks, the old-growth preserved in Memaloose Creek Canyon is exquisite. The trail up the canyon wanders among huge Douglas firs, surrounded by rich carpets of vanilla leaf, oxalis, and bunchberry. And if you continue past the lake to the summit of South Fork Mountain, on clear days you'll spot every Cascade peak south from the Three Sisters, north to Mt. Rainier.
Start at the unmarked trailhead on Memaloose Road 45, just before the creek crossing. The trail gradually gains elevation as it heads up canyon; the clear- cut slopes you noticed on arrival have all but disappeared, now engulfed by enchanting forest. After several creek crossings and a few short switchbacks, the trail deposits you at the woodsy shore of Memaloose Lake, filling an ancient glaciated cirque. A light path to the right goes about 50 yards to a small, private campsite at the lake's edge. Turn left, over the lake's outlet, to several larger campsites, and the continuing trail up South Fork Mountain.
Though the sign indicates the trail beyond is not maintained, it remains in good shape, and is fairly easy to follow. The next mile switchbacks up the side of the canyon to the top of the ridge, then ends at the summit plateau, and site of an old fire lookout. From a viewpoint on the northeast corner, spot Mts. Hood, Adams, St. Helens and Rainier; from the south side of the summit, spy Mts. Jefferson, Washington, Broken Top and the Three Sisters. Pick your view, take five for a snack, and when you're ready, return by the same route.
