Don’t be fooled by the title; a lot of the area covered is in Colorado, including Denver, Boulder and Ft. Collins. This is a very good plant ID book from by Mary O’Brien and Karen Vail with interesting descriptions. In addition, it’s an excellent herbal, giving both medicinal and edible uses. Highlighted in yellow are important “cautions”. It is presented in a respectful way, honoring nature as did the Ute Indians who pioneered the use of these plants. For example, did you know that Gambel Oak “…is a good back country first aid plant to know, using the leaves as a poultice or wash for insect bites and wounds, or chewing a piece of the bark for toothaches….” Good photos. These local gals really know their stuff and we highly recommend their book!
