Colorized photograph of Fort Callville on the banks of the Colorado River.
Transcribed Notes: Transcribed from back of postcard: "Fort Collville (sic) on the Colorado above the Hoover Dam was established in early days as a trading post and terminus for river boats plying up the river from the gulf to this point. The old fort will be entirely under water when the lake is formed by the construction of Hoover Dam."
