A view of the entrance to the historic Salt Lake Stock and Mining Exchange Building. Built in 1909 of sandstone and brick, the building has classic Roman and Greek Architectural features, including ionic pillars and a triangular roof. The Exchange played a role in the West’s history as a financial center for the region’s mining activities. It was significantly impacted by World Wars and the Depression in the early part of the 20th century, but saw a revival during the Uranium boom in the 1950’s. In 1954, more than 30 million shares in uranium companies were traded through the exchange. The exchange closed in 1986.
