Hikers

The men and women from California and Nevada posed with their arms around each other before trying to climb and swim through the popular sandstone gorge. Days later, rescuers searching for their bodies found the camera, revealing the final image of the group before they died.

Within hours of entering Keyhole Canyon, dark skies unleashed fierce rains that sent water surging through the chasm, sweeping the group to their deaths Monday.

The park named the men and women, six from California and one from Nevada, who died when a flash flood rushed through the canyon earlier this week. Their identities were released after rescuers traversed a 100-foot drop into a rugged terrain to find the last victim's body.

Known as a slot canyon, the passage is as narrow as a window in some spots and several hundred feet deep. Flooding can turn such canyons into deadly channels of fast-moving water and debris in just minutes.

A sudden deluge of rain fueled the flood, which "went from a trickle to a wall" of water, park ranger Therese Picard said.
