Highway 180 bisects the Museum of Northern Arizona campus

Besides the inspiring exhibitions, the Museum of Northern Arizona has 200 acres of land, including gardens, trails, a library, and many historic buildings. Some of the outdoor spaces are open to the public, such as the gardens and trails. Collections areas and research laboratories occasionally offer Behind-the-Scenes tours. Other areas, including the Discovery Village and Pearson Hall, are used for public programs and private events. Highway 180 bisects the campus, with the museum building on the south side of the busy road and the other facilities to the north. When visiting the campus, please respect that you are on private land where people are working.

Built in the 1880s, this log barn is one of the original structures from Thomas McMillan’s homestead. Sawdust insulates the space between the double log walls to create a cool storage area for potatoes and other crops.

Hilltop (Facilities Office)

Now used as offices, this four-room frame cottage was built in 1927 for the farmer who leased the farm operations from Mary-Russell Ferrell Colton. Since then it has been renovated and enlarged several times.


A wing was added to the administration building in 1963; it was built by US Geological Survey funds to house the astrogeology branch of USGS. The space was later turned over to the MNA Anthropology Department and additional rooms were added to provide bulk archaeological storage.

Originally built as dairy barns in 1935, these malpais structures are now used as botany and ecology labs. The floors had chipped cement to keep cows and calves from slipping and a walk-in cooler used for keeping dairy products. It was converted into offices and labs for geology and biology in 1945.

Brady (Geology)

This structure was built with National Science Foundation funds in 1966 and contains six offices, a conference room, dark room, vault, storage areas, study areas, and preparation rooms. It is named for longtime MNA geologist “Major” Lionel Brady and houses the Geology Department and collections.
