Crystal Lake Recreation Area is part of the San Gabriel River (formerly Mount Baldy) District of The Angeles National Forest in California. It consists of a lake, a public campground, and Deer Flats, a group campground. It is located approximately 26 miles (42 km) north on Hwy. 39 heading out of Azusa, California at the headwaters of the North Fork of the San Gabriel River at an elevation approximately 5,200 feet (1585 m) above sea level.
The area around Crystal Lake, before there was a campground and resort, was referred to as Pine Flat. The Lake was called Sycamore Lake by R. W. Dawson who lived at Sycamore Flats down the hill. The lake has no sycamore trees, so the name was obviously derived from Dawson's place. The area was a great draw for grizzly bears as they seemed to prefer the lake waters to the stream waters down the hill. It was thus a very dangerous place for a human to be without a firearm of some sort. Frightful grizzly bear stories abound from the middle 1860's.
