An aerial view of Alcatraz Island in San Francisco Bay, with the prison complex, lighthouse, and rocky shoreline ringed by water and hills in the distance. In the 1910s the island was an Army post and military prison, not yet the federal penitentiary it became in 1934. The lighthouse was the first on the West Coast.
