White-nose syndrome, a disease often fatal to bats, has turned up in Carlsbad Cavern at Carlsbad Caverns National Park in New Mexico.

Two climbers, exhausted and battling hypothermia, remained stuck Thursday high on Denali where they were awaiting rescue in a "crude snow cave." Climbing rangers from Denali National Park were awaiting a break in the weather at a high camp at 17,200 feet on the 20,310-foot mountain, roughly 2,400 feet below the stranded climbers.

Two climbers were stranded Wednesday high on Denali by frostbite and hypothermia, while another member of their team who had managed to descend part of the way from the 20,310-foot summit was rescued.

Halfway through a one-hour set, the Arrowhead Jazz Band stops for 15 minutes and invites questions from the audience. It’s an unusual move from an even more unusual band made up partly of park rangers.
