Floor of Valley Sinks After Quake
January 21, 1951
Drop in the floor of Long Valley, Lassen county, as much as ten inches, has been discovered along one side of a crack in the earth in the Doyle area, apparently the result of the series of earth quakes in December.
The ground has sunk along one edge of the crack from two to six inches in width running along the foot of Fort Sage mountain, about a mile northeast of Doyle. Depth of the crack varies from a few inches to six feet.
The course of the crack has been followed by observers in a jeep for more than four miles. The drop in the ground is very noticeable, and causes a major bump in the road crossing.
Prof. Vincent Gianella of the geology department of the University of Nevada, spent several days in the area last week making a study of the drop.
Several wells in the area have gone dry as the result of the earthquakes, according to Pete Zamboni who operates a garage at Doyle, and whose well has gone dry.
