Mariposa-Yosemite Airport/Mariposa Auxiliary Field (site) (KPMI)

In 1942, the United States (U.S) acquired 60.442 lease acres from the County of Mariposa, 0.364 lease acre from John Marre, and 1.388 lease acres from Richard and Willa May Morrissey. The total acreage acquired for the site was 62.194. The property acquired from Mariposa County existed as the Mariposa County airport prior to the U.S. lease, which was built around 1937. The remaining leased acreage was used as an easement to a radio beacon located on BLM property atop Mount Bullion. The site was used by DoD as an emergency landing field and auxiliary to the Merced Airfield, since the site is located at an altitude above the typical valley fog layer.
