Mears Peak combines well with S.7 but not so well with S.6 because of technical problems along the connecting ridge. Mileage and elevation gain provided for Mears does not include continuing to either summit. See S.7 for details on the Mears to S.7 traverse along the connecting ridge.
From a campsite at 10,800 ft., or if you've walked in to do Mears as a day hike, look at the south facing slopes below and west of the summit. There will be several parallel tundra/grassy slopes separated by rubble-filled gullies. All of these slopes terminate higher up because of rocky outcrops and cliffs. Cross the creek and head up the slope farthest to the right. Gain as much elevation as you can on the tundra/grass. Eventually, the greenery will give way to small, rocky talus that slides away with each step. Once you leave the tundra/grass, you will be on broken rubble, scree, talus, etc., the remainder of the climb. Gain elevation until a cliff stops further progress, then angle east and north to avoid the cliffs and look for a break to continue on up. The footing will not improve. At times, the talus thinly covers sloping slabs of rock, making footing even more treacherous. As you continue to angle upward, you may find a small gully of solid rock that can be climbed with some 3rd class scrambling. Above it, you will emerge onto yet another talus-strewn slope. Hike in the direction of a small saddle west of the Mears summit. Once at the saddle, stand upright again, at least for a short time. If you go earlier in the summer, you may find some snow covering the talus. The angle is steep enough where you would probably want ice axe and crampons or at least, micro-spikes.
From the saddle, pick a route to the summit of Mears, still east of your location and another 500 vertical feet of gain. Be grateful for the somewhat better footing. When you reach the split summit, the view will help relieve the tension of the climb. To the north - the open lowlands of the western slope. Immediately around you, the contrasting rugged peaks. To descend, return as best you can by the same route. Be careful on the scree - this stuff, once it begins to slide, may not stop. If you haven't had enough already, continue west along the ridge to S.7, a 3rd class ridge traverse of well over a mile in length.
An interesting side note: The summit register we found on Mears recorded that Kent Beverly of Grand Junction had climbed Mears from its NE couloir, which he indicated he had attempted 5 times before succeeding.
