The Santa Ana River Guide: From Crest to Coast-110 Miles along Southern California's Largest River System reveals both the wild and urban sides of the Southland's most important river. The book relates the river's natural and human history, geology, and current conditions and provides all the information necessary to plan an outing on or near the river. Organised into six geographical sections corresponding to the river's "reaches," the book's individual entries include an extensive description of each park and preserve, location and access information, and highlights of what to do there. In addition to covering the recreational possibilities, the book is a call to action for further protecting and restoring the river.
