RiverMaps Guide to the Middle Fork and Main Salmon Rivers, Idaho [4th Edition]


76 pages with 32 maps, 184 miles, color photographs and shaded topographic relief. Includes the rapids that were new or changed through late 2011 and many Class II rapids that were omitted in the 1st Edition.

Mile 4-6 on the Middle Fork – Severe debris flows in 2022 blocked the river with logs, debris fans, and a destroyed pack bridge. The river cleared some of this out, but conditions were poor in late 2022. High water in 2023 will begin to rearrange things, but it will be some time before conditions stabilize.

RiverMapsTM map books “go with the flow”. Each map is oriented so the river flows upward on the page like you’re looking downstream. No more turning your map upside down or twisting your head to read it.

These high-quality spiral-bound guidebooks are offset-printed on plastic pages measuring 8-1/2 x 14 inches. The covers are plastic card stock. The entire book is waterproof and tear-resistant (but not indestructible!). The guidebooks include mile-by-mile descriptions of campsites, rapids, and points of interest and include many color photographs. The spiral bindings and stiff covers make them lay flat and easy to use.

They are printed with USGS 7.5′ topographic maps as the background at the original map scale of 2,000 feet per inch.

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 guidebook 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.

We just got back from a Grand Canyon trip 2 weeks ago. We totally abused our Whitis/Martin guide. It stayed out all day, all night, was wind-blown, sand blasted, stepped on and wet for 18 days. It came through amazingly well. Our notes written with not-so-permanent marker washed off, but all pages in the book are in tact. It got packed wet for the trip home, and a few days later we layed the book on a table , periodically turning each page to air dry and blow the grit off. No stuck pages, the book looks almost new and is ready for another trip. In addition to being durable, a well laid-out river guide!
