Jalama County Beach, California:  May 17, 2016

This point is as close as the public can get to the southwesternmost point of the contiguous United States.  The southwesternmost point is located near Point Arguello on Vandenberg Air Force Base, near Lompoc, California.  But because it's on an Air Force Base, it's off-limits to the public.  You can barely see the point in this panorama.  

I'd never heard of Jalama County Beach, even though I'd lived in California for 15 years.  It's at the end of a dead-end, 14-mile road and there's a nice campground here.  I camped here one night and, like the true extreme geographer that I am, made sure that I was closer to the southwesternmost point that evening than anyone else!
