Aftermath of the W.W. Eastman tunnel collapse that caused the loss of St. Anthony Falls to erosion. This image is by Arthur Adams, Minneapolis high school teacher, local historian, and photographer. Adams traveled throughout Minnesota, taking photographs to augment his lectures. His studio was located at 3648 Lyndale Avenue South in Minneapolis.
Fill in the east channel of the Mississippi River just below the Central Avenue Bridge; the dotted line shows the face of a stone wall built on the bank years before.
This picture shows the amount of filling in done by Eastman; the fill extends from the bank on which the rocks are shown over to the extreme right hand side. The materials consisted of loose sans and some mud; rock was piled in later and little rock was used in the lower fill. Also shows Nicollet Island and the Hennepin Avenue bridge.
