Karcher Mall is an enclosed shopping mall located in Nampa, Idaho, U.S.. The mall opened in August 1965 with Buttrey Food & Drug, Rasco-Tempo, and Skaggs Drug Centers as anchor stores. The mall was the largest shopping center in the Treasure Valley until 1988 when the Boise Towne Square Mall was opened in Boise. The new mall directed traffic away for the Karcher Mall and several retailers, including 20-year-old anchor JCPenney, departed the mall to move to Boise. Since then, the mall has been sold to numerous owners, each of which attempted to revitalize the mall to mixed results.
