The original description says: These photographs may be sufficient to show general character of large boulders as previously existed at Spokane rapids over a wide area, but which were broken and leveled down, or blown entirely away, by the improvement work. Later photographs show the ground leveled down. The main point should now be further cut out and large boulders destroyed over other areas. The process consisted mainly in drilling the rocks and breaking them successively into small bits.
Between 1907 and 1913 the U.S. Army Corps of Engineers undertook to survey and photograph the Columbia River. In this pre-dam era, the Corps was particularly interested in documenting navigation hazards and parts of the river that were unnavigable. The images from this collection show the river as is was before a series of dams built in the 1930-50s tamed the river.
