As demand for EV388A grew, the Environmental Program faculty searched for innovative ways to address the increased enrollment as well as to enhance cadet learning. This ultimately led to the creation of EV399A, the Geology Field Course, in 1990. EV399A also fulfills the Academic Individual Advanced Development (AIAD) graduation requirement. The three-week course was originally designed so that the first week was spent at West Point and the remaining two weeks at the United States Air Force Academy (USAFA). The week at West Point focused on establishing the geologist’s toolkit for experiential learning. The two weeks in Colorado enabled a wide variety of hands-on geology experiences, which are difficult to replicate in the Northeast. Additionally, the course provided a platform for a joint learning environment, with USAFA and USMA instructors teaching the course to cadets from both academies. EV399A ran continuously from 1990 until 2006, when the course was placed on hold due to curriculum changes at USAFA and increasingly prohibitive travel costs.
