Io completed HALS UT-5 of the Union Stockyards in Ogden, Utah. As a prominent western railroad hub, Ogden was once home to the largest livestock market west of Denver. In 1929, the stockyards processed over 250 carloads of cattle, 200 carloads of sheep, and 100 carloads of hogs every single day. Io worked to document the expansive history of this unique site by completing a working history, as well as creating measured drawings and photographs. The work was completed as part of Ogden City’s mitigation for compliance with Section 106 of the National Historic Preservation Act for redevelopment of the site using HUD funds.
