L M Clayton Airport — Wolf Point, United States

OLF is the code for L M Clayton Airport, serving Wolf Point in northeastern Montana, United States. Named after a local aviation figure, this small regional airport has historically received subsidized commercial service under the Essential Air Service program, connecting the remote Fort Peck Indian Reservation area to larger hub airports like Billings. OLF primarily supports general aviation, agricultural flights, and occasional medical evacuations given the vast, sparsely populated ranchland surrounding Wolf Point. The airport's single paved runway accommodates small turboprop aircraft rather than jets. For a town far from major highways, OLF represents a vital transportation lifeline for residents, businesses, and emergency services in this isolated corner of Montana.
