From the Elizabeth Harrington Photograph Collection (PH-00291). Inscription with image reads: "Potosi Mountain. (1917) Potosi mine can be seen near the top of the mountain. The structure below is the calciner where the ore brought down from the mine was roasted to separate the metals from the rock before being hauled by big power trucks to Arden to be then loaded on to railroad cars to go all over the country. Potosi Mountain was the scene of the disastrous air crash that took the lives of screen actress Carol Lombard and her mother in 1942." - E(lizabeth) Harrington.
