Revised and Updated October 2020: CreateSpace, Amazon's print-on-demand service, is now integrated into the Kindle Desktop Publishing platform (KDP). This means that you can manage all your titles, e-book and paperback, from the KDP Bookshelf. The text has been completely revised to reflect this, although the subtitle of the book still refers to CreateSpace.
Both the print and the Kindle editions of Exploring Grand Canyon have been revised and updated as of June, 2020, as well as the companion website, ExploringGrandCanyon.info.
Revised and updated April 2019 to include GLONASS and Galileo GNSS (Global Navigation Satellite systems) and an updated list of mapping software and other resources, as well as many other changes and updates. Available on Amazon.
