Elevation of Montana Cities and Towns. The elevations here are estimated from a the U.S. Geological Survey/Defense Mapping Agency Global 30 Arc-Second Elevation Data Set. Elevations from this data set may be off by as much as 125 feet. The latitudes and longitudes used to estimate the town elevations were taken from the U.S. Geological Survey Geographic Names Information System. Some towns may, of course, cover areas that have a great range of elevations.
