What really happened to Old Man Graham?
Tuesday, May 5, 2015 — Oh, it must have been one heck of a mighty day when Lassen Peak violently erupted May 22, 1915 and hurled volcanic ash as far as 200 miles to the east — the last eruption in the Cascade Range except for Mt. St. Helens, which exploded in Washington state in 1980.
I’ve been to the top of Lassen Peak, and looked down into the two craters the eruptions created. Scanning the horizon from the summit, Mt. Shasta looms large in the distance, and looking back toward Lassen County one can see the Caribou Wilderness and Lake Almanor off to the east.
