Trails of the Cordilleras Blanca & Huayhuash of Peru by Jim Bartle (1981)

Iconic old-school hiking guide to the Cordillera Blanca and Cordillera Huayhuash in Peru. While not a climbing guide, this slim little book contains a ton of useful information about trail systems, passes, transit routes, and more. Although this book is now almost 50 years old, Peru is a place of slow progress, especially in the mountains - much of it has not changed. I have personally been to the Blanca and used this book - it remains useful.

159 pages, b&w with an insert of color photographs in the middle. Many detail maps throughout and a regional overview map in a pocket in the back,
