Guide to the Upper Salt River, Arizona
28 pages with 7 maps, 53 miles, color photographs, and shaded topographic relief.
These spiral-bound guide books are offset-printed on plastic pages. The covers are plastic card stock. The entire books are waterproof and tear resistant. Guide books include mile-by-mile descriptions of campsites, rapids, and points of interest and include many photographs.
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.
