In the distance is the beginning of the west side excavation for the dam. It was the area directly behind this cut that subsequently became involved in the extensive west-side slides. In the foreground is the Seaton Ferry and the Seaton...

By March 27, 1934 the slide material had slipped considerably. Note how the earth had flowed as the excavating equipment removed the supporting base. Drilling operations for exploring the water seams are just getting started.

This is the beginning of the downstream arm of the Westside cofferdam, in December of 1934. This structure was destined to be the largest of its kind ever constructed. The importance of the cofferdams installed during the first contract can...

The most precarious, and perhaps the most spectacular phase of the construction program, was the diversion of the river. This matter of river control required an exacting performance of construction operations to conform with the cycles of river...

This view taken in the spring of 1935 shows how the early excavation on the east side was conducted with power shovels and trucks; the material being dumped in the forebay area upstream from the dam. Later conveyor systems running to this spoil...

Here at Grand Coulee Dam, construction methods and mechanisms were extended to new horizons. The conveyor system of handling muck began with the members of the MWAK Co. In 1931-32 the Silas Mason Co. used such a system in construction of the...

Bedrock was generally found at elevation 875, or some 60 feet below low water level. The overburden in the river averaged about 30 feet thick, with clay comprising about 90% of the volume; hard as rock when dry and slippery as grease when wet....

Here is shown the river at flood stage during the spring of 1936. The east cofferdam area has been deliberately flooded to save the temporary wooden cofferdam. Work on the east end of the MWAK high trestle has been suspended, but erection of the...

In the foreground removal of the upstream arm of the west cofferdam is well advanced. This will permit the river to flow on this side of the remaining part of the cofferdam when the cross-river cofferdams close off the main river channel. About...
