Using information given in the article, I used Google
Earth to find the the location of the structure, which
it discusses. The latitude and longitude of this
structure is:
108.6729941879148 W
47.82294379843308 N
It is on the edge of hills known as "The Little Rocky
Mountains". There a number of circular structure
within the region associated with laccolithic intrusions.
There is a discussion of this in "Geology and Physiography
of Fort Belknap" at:

The Geologic Map of the Zortman 30' x 60' Quadrangle,
Central Montana can be downloaded from:

and

Two publications on the geology of the area are:
Knechtel, M.M., 1944, Oil and gas possibilities of the
plains adjacent to the Little Rocky Mountains, Montana:
U.S. Geological Survey, Oil and Gas Investigations
Map OM-4, scale 1:48000.
Knechtel, M.M., 1959, Stratigraphy of the Little Rocky
Mountains and encircling foothills, Montana: U.S.
Geological Survey, Bulletin 1072-N, scale 1:48000.
