[6][3] On the morning of February 15, 1932 customers began a run on the bank, waiting in lines that ran out of the building and onto the street.

"[7] Lines of depositors that had been as long as a city block began to dwindle, and within five or six days many customers returned to deposit their money.

By month's end, total deposits were more than withdrawals, and Zions had survived the Great Depression.

In April 1960, Keystone, together with several individual investors, acquired a 57.5% interest in Zions First National Bank from the LDS Church.
