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

a great range of elevations.
