Mazamas Making Their Way up the Hogsback towards the Summit of Mt. Hood, 1963

Retired Forest Service employee and current avalanche safety expert Roland Emetaz—also known as Mr. Em—shot this photo of Mazamas club climbers on Oregon's Mt. Hood scaling the mountain's Hogsback ridge, which runs from Crater Rock to the so-called Pearly Gates and the summit. Inspired by the Nahuatl Indian word for "mountain goat," Oregon mountaineers, male and female, founded the adventuring club Mazamas (pronounced "mah-zah-maz") on the mountain's summit in 1894.
