Yuma’s Colorado River State Historic Park, which was an Army Quartermaster Depot from 1869 to 1884, hosted a free public event for the Army’s 250th birthday on June 14, 2025, and U.S. Army Yuma Proving Ground (YPG) was there. The event, which ran from 9:00 a.m. to 1:00 p.m., drew crowds in the high hundreds before record temperatures hit Yuma in force.
