Inscription.

The 30-inch core samples behind you were removed from the concrete foundation of the dam to allow access for future grouting and for a means to measure uplift pressure on the dam.

The sandstone samples on the west end are typical of preconstruction soil tests made to determine if the ground in this area could support a large concrete gravity dam.

First proposed in the early 1930s, the dam was initially rejected because of its remote site and Depression conditions in New Mexico. However, the dam was made a possibility in 1935 with the passage of the Emergency Relief Appropriation Act, which authorized several public works projects in New Mexico to provide relief to unemployment. Initial site work began in 1935 with construction on the actual dam starting in 1936. In 1939 construction was completed at a cost of $15.8 million. Source: Wikipedia
