Ribbed Peak can be combined with UN13,100B as a very full and long day hike. The traverse from UN13,100 to Ribbed may take from 2 - 3 hours. You can read more about that traverse under UN13,100B. For those who may like to backpack in as far as Fairview Lake, we offer this little bit of "approach" information.
From the trailhead parking, a well-marked and used trail #1915 heads out NE across open meadows before entering aspen forest. In later June, the wildflowers in this meadow and throughout the lower elevation forest are amazing. The trail exists to skirt the private property around Wood's Lake, so it gradually gains nearly 400 feet in elevation for the first mile before losing much of that elevation to drop back down to and reconnect with the road that exits the property at its east end and continues to an old building and a sturdy bridge across Lime Creek. There's a great campsite shortly before that crossing.
Once across the bridge, there's a Wilderness Registration where you can obtain your permit for overnight camping. Immediately after, the trail climbs up steeply and then quickly levels to wind its way east back to Eagle Lake. It gains elevation in pitches with intervening level areas. There's a waterfall on Lime Creek along the way.
When you arrive at Eagle Lake, (about 1:45 from the TH) you must cross the western outlet on a log jam mass to resume the trail along the north shore of the lake. Not long after crossing are some "designated" campsites. Midway along the north shore is another good camping area near where a promontory juts into the lake. Beyond the lake, the trail heads into forest, crosses into an open area which is the bottom of an avalanche chute that you use to access UN13,100B, then re-enters forest. There is an area of downed timber that makes following the trail difficult. Beyond Eagle Lake, we don't think the trail receives maintenance anyhow. Do the best you can to follow it to Halfmoon Lake and beyond there, the trail becomes a little more evident, except for where it crosses an open, grassy meadow. A little bit before Fairview Lake, the trail gains elevation steeply and then crosses a small rise to offer a splendid view looking down onto the lake. Walk around the north shore of the lake to the eastern an excellent and large campsite.
Best camping spots on the approach are: 1. Just past the eastern end of the Wood's Lake private property where the bypass trail joins back in with the old roadbed; 2. At the designated sites along the northern shore of Eagle Lake; and 3. The eastern end of Fairview Lake above the inlet maybe 50 - 100 yards in some trees. This site could accommodate several tents. Trout abound in the nearby stream & there's a small double waterfall & pool.
