The RiverMaps Guide to the Colorado River in the Grand Canyon is a must-have guidebook for your trip down the Grand. The USGS topo maps are durable, waterproof and offer excellent descriptions of the river features.
Our spiral-bound guide books are offset-printed on plastic pages. The covers are plastic card stock. The entire books are waterproof and tear resistant (but not indestructible!). Our guide books include mile-by-mile descriptions of campsites, rapids, and points of interest and include many photographs.
Care of Your Books
You can write on dry plastic pages with an indelible marker like a Sanford Sharpie. If your offset printed map or guide book gets wet, don't worry! It can stay wet without damage. You will eventually want to dry it out with a rag or by turning and air drying each page. The pages usually won't stick, but... Don't cook your books! We have seen some books with pages that stick, especially where the ink is heavy over photographs. The only way we are able to reproduce this effect is to let a wet book dry for an extended time in the hot sun. You should avoid leaving your book in the direct sun or a hot vehicle or trailer for any longer than necessary. Day-to-day use in the sun while on the river has never been a problem that we've seen. Don't freeze your books! We have seen books that were wet and frozen lose some of their ink and underlying coating that holds the ink to the plastic page. If your book is wet and frozen, we suggest either letting it defrost or dipping it in the river for a minute to melt the ice and allow the pages to separate.
Errata & Revisions
We will make corrections in future printings of our books when we become aware of needed revisions. All of our current books address comments that we've received, so there are no pending revisions of consequence at this time.
