Very sad story...a pair of missing hikers, a father and son, were found dead in Carlsbad Caverns. From the story:

The extraordinary heat wave gripping the western United States has so far been blamed for at least four deaths, authorities said Wednesday.

The bodies of Robert Stuart Pluta, 57, and his son Bobby, 21, of Corpus Christi, Texas, were discovered Monday and Tuesday respectively, in Carlsbad Caverns National Park in New Mexico, where daily high temperatures have topped 100 degrees for almost a week, New Mexico State Police said Wednesday.

The Plutas, both of whom were experienced hikers, had been on a hiking trip since Wednesday of last week but hadn't been heard from since they checked into their hotel, NBC station KRIS of Corpus Christi reported. A parkwide search was launched on Monday.



Apparently they took a father-son trip over Father's Day and had been out of contact for a couple of days. Not a lot of details but presumably lack of water and heat combined to kill them. It's a sad case but a reminder to everyone to be especially careful in extremely hot weather.
