Copper ore was hauled over road to Keddie where the ore was loaded into Western Pacific Railroad freight cars and transported to the ASARCO smelter at Garfield, Utah.
Road transport was replaced by rail in 1917 when the Indian Valley Railroad opened.
In 1918 the townsite of Engelmine, or Engel, was laid out and gridded near Lower Camp.
In 1930 the Engels mine was closed due to the declining value of copper.
The houses were moved to Greenville, Quincy and Portola and the last cabin was removed in the 1960s.
