 Death Valley National Park says one person has died from heat exposure and another's been hospitalized after visiting the park Saturday. Here's CBS's Carter Evans. It was a group of six motorcyclists, and they were all riding through Death Valley there, and it's extremely hot. I mean, this is the day when they've got those record temperatures of 128 degrees. So there are six of them. They're all riding in a group. Two of them come down with some sort of heat-related illness. That's all we're being told right now.
