Photograph of a large bus parked in front of the administration building, Lake Arrowhead, ca.1950. The bus can be seen facing left to the right of center with the words "Mountain Auto Line" painted on the side. Bushes can be seen surrounding a pile with a sign attached to it reading, "Administration Building. Arrowhead Lake [...]. Lake Arrowhead [...]. Lake Arrowhead [...]". Two-story buildings can be seen behind the bus and sign. Two men can be seen at left, while a man and a woman can be seen walking down stairs. Sunlight streams through the pine trees in the background, while what appears to be a portion of a car can be seen in the extreme right foreground.
