I just noticed something else: The UC Berkeley Library map showing the trail down Charlotte Creek is different from the pdf file in the top post in this thread. The pdf file is of the 1927 reprint, while the library version must be the 1907 version.
...Because that Charlotte Creek trail is GONE on the later version. And instead, the later version shows a trail going up Bubbs Creek, through Center Basin, over Junction Pass, and then back over the crest at Shepherd Pass. That trail is missing on the 1907 map.
