SEKI has given me approval for the 19th.
If anyone is interested in this trip, there are multiple options he/she could do, short of completing the whole route:
Go to Sphinx lakes Basin, then return to Road's End-- beautiful lakes, interesting cross-country once off the Avalanche Pass trail.
Cross Longley Pass, descend to Reflection Lake or East Lake, then head back on trail to Road's End.
Cross Kings/Kern divide at Thunder Col, then cross back via Milly's foot path, descend to Reflection Lake & back to Road's End.
Cross Milestone Mtn. Pass, intersect Colby Pass trail and head back on trail via Colby Pass, Cement Meadow, Roaring River, Avalanche Pass, all on trail, to Road's End.
Cross Triple Divide Pass, go down Cloud Canyon (off trail, but open country until the very end), rejoin Colby Pass trail at Cement Meadow, then on trail back to Roaring River, back over Avalanche Pass to Road's End.
Cross Lion Lake, Lion Rock, Kaweah Gap, then on trail over Elizabeth Pass, down Deadman Canyon to Roaring River, over Avalanche Pass back to Road's End.
Any one of these would be a great trip, and the options allow for differences in available time, how one is feeling, etc. Depending on how I'm doing, I may choose one of the shorter options myself. Or, if everything is going splendidly, and I have food & strength left, may investigate Glacier Ridge, after the homeward/second crossing of Lion Lake Pass.
