I used the National Geographic TOPO! series to create these maps. I downloaded the .tpo file from the Map Exchange. This file was posted by Dan Braun, Founder of Southern Yosemite Mountain Guides. All map notations are from that file and not checked by me, yet! The maps are formatted to fit on a regular size piece of paper. The full size map image is larger, so you can scale the map to larger sizes.
NOTE: See link at bottom of page to download whole series in one file. Follow link for instructional guide for correctly printing maps.
