PORTLAND, Ore. -- A man who died while hiking with his dog at the Columbia River Gorge was identified as 70-year-old Joseph Kohut of Portland.

Authorities said a dog helped point out Kohut after he fell more than 100 feet from the top of Triple Falls.

A volunteer firefighter said he noticed the dog sitting at the top of the falls, looking over the edge of the cliff. The firefighter then noticed the man's body below.

A team of rescue workers treated Kohut but were unable to save him from severe head injuries.

At about the same time, a family of five was rescued in the area when a rock slide dropped on them.

The father threw himself over the children to protect them.

He suffered head injuries.
