Lookout Peak is found in the Little Lakes Valley, Secor says the peak has also been called "Tempest Peak" and "Ruby Peak". One can climb this peak in a short period of time from Mosquito Flats Trailhead. In fact its probably the quickest summit to attain in the area, with mostly class 2 and some optional, fun , easy class 3 from all sides.
In the winter shot shown above, Ruby Lake is frozen and lookout peak is the one on the left of the photo. I have seen many a cross country skier cross the frozen lake and gain access to Mono Pass from there.(see photo below)

Getting There

Lookout Peak
From Highway 395 exit at Toms place, cross the frontage road and head Southwest on Rock Creek Road,(the only rd heading this direction) drive about 10 miles to Mosquito Flat trail head at the end of Rock Creek Road, 10200'+, toilets and bear boxes here. Find the trailhead at the South end of the Parking lot. The trail quickly divides, head toward Mono Pass(signed)and just prior to the switchbacks up to the pass you will see the fork to Ruby Lake(signed). From Ruby Lake you can take the North ridge to the summit or stay on the east side of Ruby and come around to the South east ridge to the summit, all class 2 and a bit of easy class 3 depending on your travel.

Red Tape

No red tape for a day hike, you will need a permit for an overnight trip, the permit also allows you to camp at Mosquito Flats. The parking lot is packed on weekends, but there always seems to be a spot.

Lookout Peak SE Ridge

You can make a climb of Lookout Peak without going near Ruby Lake. From the north shore of Long Lake, head northwest up a large area of black rock, making for the foot of the narrow, granite upper Southeast Ridge. Ascend the ridge directly (an enjoyable Class 3 outing). Either retrace your route or descend the North Ridge to connect with the Mono Pass Trail.
