I’ve finally transferred the information in a National Geographic Topo! file to Topo! Explorer online. I was waiting for National Geographic to update the Topo! Explorer desktop software to solve a number of usability and accuracy problems, but this has not happened in many months, and I suspect they have abandoned software development. Nevertheless, the interactive online version may be of some use to you, so I’ve shared it through Topo! Explorer online, at http://www.topo.com/trips/2364-granitechief.
