The fourth edition of Martin's popular hiking guide for river runners has been updated with mile markers on the maps corresponding to those set by the GCMRC and which match the current edition of Martin and Whitis's Guide to the Colorado River through Grand Canyon.
- Author: Tom Martin has hiked and rafted extensively in the Grand Canyon and enjoys sharing his experience with others. He says the Grand Canyon is so much more than the river and if you know there's a route up a side canyon you should take it. He has recently built a replica of the first dory in Grand Canyon in the 1950s, the GEM, and has published a book about river running in the Grand Canyon prior to the building of Glen Canyon Dam called Big Water Little Boats.
