The Sierra Madre of Mexico has a hidden treasure in its steep rivers that flow through rugged canyons that are can be deeper than the Grand Canyon. Vegetation varies from desert to tropical. Exotic birds and animals are found such as parakeets and parrots. Many areas of Mexico are limestone karst where springs abound and rivers can disappear underground. These areas have rivers that are formed by deposition of minerals forming waterfalls that are both visually stunning and quite different from rivers formed by erosion.
This book shares information gathered from over twenty years of adventures and explorations. There are 56 detailed river run descriptions on 37 different rivers along with 24 detailed maps and 32 color photographs.
