Many of the swimming holes featured on this blog can be found in Pancho Doll's book entitled "Day Trips with a Splash - Swimming Holes of CA". We respect the author's copyrights. Therefore, for more information you will need to buy the book at http://www.running-water.com. We visited most of these sites during the Summer of 2009 and 2012. All photos Copyright Timothy H.
