Nine Baldy Area Peaks Professional Review and Guide
"This is the mother of all hikes in Southern California. It tours nine major summits around San Antonio Canyon: Ontario, Bighorn, Cucamonga, Timber, Telegraph, Thunder, Harwood, Baldy, and West Baldy. There is substantial elevation gain and loss between most of the peaks, making this the toughest of the multi-mountain challenges in this book. Standing on top of Ontario Peak at dawn, mighty Mt. Baldy beckons to you from across the deep canyon separating the peaks. Standing atop Baldy at dusk, you will look back at the dramatic ridges of Ontario. This is a great trip to do when there is a full moon because the extra light may be helpful. Bring a headlamp, a generous supply of water, and boundless enthusiasm."
