Since 1969, our durable, full-color river guides have helped thousands of boaters explore the Colorado River through the Grand Canyon, the Green and Yampa Rivers in Dinosaur National Monument, the Colorado and Green Rivers and Cataract Canyon through Canyonlands National Park, and Desolation and Gray Canyons on the Green River.
Each guidebook features mile-by-mile river maps highlighting campsites, rapids, side hikes, historical sites, and geological landmarks. Designed for both private trips and commercial outfitters, Belknap’s guides are waterproof, tear-resistant, and built to withstand the rigors of multi-day expeditions.

As in our print version, the river runs upwards so you can always watch as you head downriver and see all the features on the map. We also show a shaded topo map that extends outside the edges of our map.
The Grand Canyon Geology Poster is a colorful, updated 18″ × 24″ wall chart illustrating the canyon’s rock layers from rim to river.It features a detailed stratigraphic column alongside river-level photographs, each clearly labeled with formation names for easy identification.This graphic slice of Earth's history is both educational and visually striking, making it a perfect addition to classrooms, offices, or home study spaces.
