Back in the 90's, a hiker on Santa Cruz Island was caught by darkness and rain, bivvied up in a convenient rock shelter, and then dialed 911 for assistance. There must have been zero GPS protocols working then, because the operator relayed the call to the city of Santa Cruz, in northern California (only a few hundred miles distant).

Once we got the location straightened out, the Park sent a boat out and a dauntless party braved a dark and stormy night to reach the beleaguered hiker. They were glad to warm themselves at the fire he had built in the meantime.
