L M Clayton Airport (OLF/KOLF) is a public-use general aviation and commercial service airport located in Wolf Point, Montana, a small city in Roosevelt County in the northeastern corner of the state. It serves as an essential transportation link for communities along the Hi-Line, a stretch of northern Montana along the old Great Northern Railway corridor. The airport is named after L. M. Clayton, a local figure of historical significance to the Wolf Point area. It operates with a single runway and modest facilities suited to the sparse population it serves. The airport receives Essential Air Service (EAS) funding, which helps subsidize commercial air service to this remote community that would otherwise be difficult to sustain commercially. Given its location on the Fort Peck Indian Reservation and surrounding agricultural plains, the airport plays an important role in connecting residents with larger regional hubs, particularly Billings, Montana, enabling access to medical care, business, and broader travel connections.
