A previous episode of As It Was described how an assistant surveyor had narrowly dodged a giant falling boulder while climbing a steep snowfield on the slopes of Mount Shasta.
The climber, B.A. Colonna, spent nine days in 1878 installing equipment and taking measurements from the 14,190-foot summit.
At the end of his assignment, he and a companion started down the mountain to where a snowfield, in Colonna’s words, “stretched out before us, beautifully white and even” for about two miles while dropping 3,000 feet in elevation. They shoved 600 pounds of tightly bundled supply packages onto the snow and watched them slide down the mountain and out of sight. The climbers descended a mile on foot, sat down on burlap bags and slid down the snowfield, using iron-spiked climbing poles as rudders.
“We were off like a shot. I have had many pleasant rides, but for rapidity and ease of motion this beat them all.” Colonna said. “This delightful ride terminated just where the packages (had also) stopped rolling.”
He added that while sliding down the mountain, “I had lost not only the gunny sack, but the seat of my trousers.”
