Found these searching around.
For those who really enjoy maps check them out.
There are a number of trails which no longer exist.
(one is across falls creek near Hetch Hetchy Dome)
(another is UP table mountain)
copy the link and then scroll down to yosemite.
You may have to install some plugin to see the maps.
If anyone has found any other maps please let me know.
I'd like to see more near Merced Lake and Rock Island Lake.
Enjoy
