Technical Slot Canyon Guide to the Colorado Plateau - Michael R. Kelsey

This is another in the series by Michael Kelsey for those who enjoy hiking and climbing. This book is unique in that every canyon described requires the use of ropes and rapelling to get all the way through. There are hundreds of maps and pictures, as well as directions and descriptions of the many small canyons available for exploration. Mr Kelsey's books have sold and continue to sell well in the Rocky Mountain region.
