An immense regrading of the City of Seattle took place at the turn of the 20th century to level the land for easier development and to extend the shoreline into Elliot Bay on the west side of the city. In scores of regrading projects, tens of millions of cubic yards were removed and relocated. One method was to use hydraulic mining to wash the earth into huge sluices and let gravity flow take the dirt to Elliot Bay. This postcard documents one of these operations in the picture AND in the notes made on the back. Later regrading was done with power shovels, conveyor belts, and specialized scows to dump the earth into the bay.
