Hunchback Mountain (Great Pyramid)

From Oregon Hikers:

This stiff hike begins from a trailhead next to the Zigzag Ranger Station on Highway 26. It is an excellent conditioning hike and the terrain is wild and rugged, especially considering its proximity to a main thoroughfare. You will hike up a rocky ridge with some picturesque outcroppings offering viewpoints: do not be surprised if you notice sign of both coyote and cougar.

The Hunchback Mountain Trail #793 begins on the south side of the parking area under Douglas-fir, western red-cedar, western hemlock, and big-leaf maple on a carpet of lady fern, deer fern, sword fern, and salal. The trail switchbacks at a spring house and rises to another switchback at the new wilderness sign and a small cistern/dam. There are two more switchbacks and then a traverse before another switchback. The trail levels at a ridgecrest of Oregon grape and sword fern and then drops to a saddle. From here, the trail heads up and switchbacks, traverses, switchbacks, and then passes under mossy ramparts. There are three short switchbacks at another rocky outcropping. Pass a campsite and then wind up before switchbacking five times to more mossy ramparts. There are three more switchbacks to higher rocky palisades and then a traverse along the slope through rhododendrons. Wind up to the ridge crest, then drop slightly to traverse the western slope of the ridge through a carpet of salal. There’s a short, steep drop down an open manzanita slope. A spur left leads to a viewpoint over the Still Creek valley. The trail drops past an andesite outcrop and then winds steeply up to the breccia/rimrock cliffs. From here, the top of Mount Hood is visible on a clear day.

The trail drops and traverses up the east side of a steep slope under Douglas-fir, hemlock and cedar. A sign points to the Rockpile Viewpoint on the right, which offers a vista of Mount Hood. The trail drops below a talus slope and switchbacks twice at a second talus field before reaching the ridge crest. Now the path undulates along, passes spur to a helispot viewpoint, and produces encounters with some interesting rock outcrops. Traverse the east side of the slope, where silver firs now enter the forest mix. Head up to a rocky crest, and make another east side traverse before reaching the crest again and a narrow andesite catwalk. Rise steeply, drop, and then ascend steeply again before reaching the sign for the Great Pyramid. Head out along this steep-sided promontory and make a couple of little scrambles to reach the end, where you can look down on the lush green cleft of the lower valley of the Salmon River.
