Yes he was. There are actually two maps, depending on whether the
observation is taken from the (so-called) terminal building, or from the
intersection of the taxiway and runway.

There are four maps per station. A short range(0-3 miles) and long
range (0-x). X depends on your terrain. When I worked at GFK the
horizon was at 10 miles so that's as far as the chart went. Here at BIL
the farthest mountains are 100 miles away so thats how far the chart
goes out. There are two charts for daytime and two charts for nighttime

I'll have to look more closely. I've only seen the two maps, and what I
noted was that they had two different observing points.

There are no landmarks visibile more than a few miles away from the ground,
and there's only one lighted obstruction (not counting runway lights) that
would be visible at night.

I'd guess that if there were a tower at EPM, visibility distances would be
greater, but from the ground, I don't think there's anything to be seen
more than three or four miles distant.
