Regarding the possible SOBO hiker reroute over Piute Pass to North Lake, then out of South Lake over Bishop Pass (or the reverse if NOBO)
In 2002 we wanted to do the North Lake-South Lake loop over Muir pass. We were two people with three llamas so we wanted to do it without a shuttle between North and South Lake.
So we had to get two permits (not an easy task). The first permit for Tyee Lakes, and the second, the next day, for North Lake. We parked at Tyee Lakes, hiked over Table Mountain and camped at George Lake, then hiked down to the Lake Sabrina trail, to the Sabrina trailhead, then Road walked to North lake and started the loop,over Piute Pass to the JMT. We spent about a week going around the loop, over Muir Pass and Bishop pass, and back to South Lake, then roadwalked back to our parking spot at Tyee trailhead. It was an elegant solution to the shuttle problem. If a shuttle between lakes isn't available, some hikers might want to walk this route between the lakes. More trail time, less road walking or hitching.
It remains to be seen what the FS will do about permissions to reroute.
