This rugged off-trail run connects Blue Canyon Trail
and Goddard Canyon Trail
. It traverses one of the most remote areas in the Sierras with many beautiful lakes and great views. It is difficult and requires good route-finding ability, but no rock climbing skills. The most difficult part is crossing Blue Canyon Pass. Although it is rated as Class 2, you need to descend a steep 30-40 yard chute on the north side. It often has snow fairly late in the season, which may require an ice-axe and crampons.
The lakes above the official end of the Blue Canyon Trail
make the long run worthwhile. Just continue up on the right side of the creek until you see easy slopes headed up through the trees. Pass the first and second of the Blue Canyon lakes and then head back near the creek where it is easiest to climb to the 3rd and 4th lakes. I went around the south end of the 4th lake and then made the easy climb up to the plateau near 10,400 feet. Lake 10401, the most beautiful of the Blue Canyon Lakes, is well-worth a short detour.
From there, cut back northwest across the plateau, around the next two large lakes, and find the easiest way up the canyon to the northeast. From near the northernmost lake, work your way up to Blue Canyon Pass, just to the right of Finger Peak. I found this difficult but doable without much exposure.
As described above, the short chute on the north side of the pass is the most difficult part of the route. If the snow is not too deep, you may be OK in the afternoon when the snow is soft. If the snow is deep or not very soft, you'll need an ice-axe and crampons. As soon as you can, turn left and make an unpleasant traverse of the talus, staying fairly high to avoid the steep slopes lower down.
Finger Col on the ridge to the west is rated Class 2, but I did not find a safe way to climb the last part. About 0.2 miles before it, you come to a safe way down to the easy slopes headed northeast. At this point, the hard part is done. The indicated route to Martha Lake is a pleasant run, at or above timberline, with great views. Some of the best lakes are a few hundred feet below the route. They are easily reached, but you'll need to climb back up to continue to Martha Pass. The lake at 10,800 feet, about 1.5 miles north of the pass is well-worth a detour.
The descent to the two lakes north of the high spot marked 11493 is somewhat difficult but doable, if you scramble down the talus to the southwest of the small lake.
Reinstein Pass is just northeast of Reinstein Peak. There are great views looking down Goddard Canyon to the north and the Ragged Spur and Goddard Creek to the south. It is easiest to take the long way around the east side of Martha Lake. It takes time and effort to negotiate the large talus blocks on the west side.
Remarkably I saw two deer about 2 miles south of Reinstein pass. I'm not sure how they get there.
