The alternate way into the Woods Lake Basin is via the John Muir Trail, either north or south. The Woods Lake Basin is to the east, between Pinchot Pass on the north, and Rae Lakes Basin on the south.
As you traverse north, you will see chutes ascending through the cliff bands above. There are any number of chutes you can take through the cliffs above you. Wingding has pictures of one way here, however she's said that it's pretty loose.
Another way is via a Chockstone Chute. This involves some nice class 2 on solid ground, with some optional fun class 3 on very solid rock. Traverse further north along the base of the cliffs, and head for the chute as seen here:
Head up towards the entrance. If care is taken, it's easy to stay on the larger talus blocks and avoid the horrid scree and sand. Once behind the large shining block, you will have the following view up the chute:
Head up to the chockstone. You have two options: either climb directly over it using some class 4 holds on the left wall of the chute, or tunnel underneath the chock, and wriggle your way up behind it. This is a fun little wriggle, but care must be taken that one is using solid rock for handholds, and not small blocks that have become stuck next to the chock.
It is easy going from here. Head up the gully, ascending mixed talus and scree, using the walls on either side as handrails (and sometimes for good foot placements as well). You can either continue all the way up to the summit plateau in the loose gully, or you can exit to the left on solid class 3 steps and blocks. If you chose this option, gain the crest of the ridge to the north of the gully, and follow it on easy class 3 rock to the summit plateau.
Once on the summit plateau, hike along to the highpoint. The higher summit is not the one with the benchmark on the map, but the west summit. The views are outstanding.
For descent, one can either go down the way one came, or head down the west ridge of the plateau to the Colosseum/Cedric Wright saddle (all class 1), which then has easy cross-country travel back to Woods Lake.
There is also a nice class 3 ridge traverse from the Colosseum/Cedric Wright saddle to Mt. Cedric Wright.
Note: Time Required is from the Woods Lake Basin. From Sawmill Pass it is either one REALLY long day, or multiple days.
