Mayflower is overseen by the state’s Military Installation Development Authority (MIDA), which was initially started to spur development by nearby Hill Air Force Base. MIDA was later expanded by the state legislature to include the ski resort, which will have a hotel with discounts for active and former military. Extell is the Mayflower developer. It purchased the resort property in 2017. Mayflower resort will be managed by Deer Valley, with Deer Valley naming, and be open for operation 25/26 ski season. Deer Valley will, effectively, double in size to around 800 skiable acres.
