The Laws Field Guide to the Sierra Nevada

With more than 2,800 original watercolor illustrations, John Muir Laws has masterfully catalogued over 1,700 species of Sierra trees, wildflowers, ferns, fungi, lichens, fish, reptiles, amphibians, birds, mammals, insects, and other small animals. This guide is designed for quick and easy use in the field. Color tabs and a unique system of keys and organization assist in the quick identification of the living things encountered along the trail.
