In the past we have visited Sunlight Peak just to make fun of it’s short stature, and historically there was John Bunyan’s little garage he used for viewing the heavens. Usually on the third Saturday one can visit the Stargazer and on the third Friday of every night at the Little Thompson there is something to see if there are no clouds. Of course these are observatories and most are identified by the dome shaped roofs apart from everyday architectural constructions we have seen (Pantheon, Hagia Sophia, St. Paul’s, most capitol buildings, etc.) plus they have some sort of telescope inside. Turns out there is another observatory nearby on the campus of CSU and it’s open on Tuesday nights:
The Madison-Macdonald Observatory (someplace behind the big bush)
Named after Marion Leslie Madison and Stewart Lincoln MacDonald who were department heads of Mathematics and Astronomy at CSU (not at the same time). These days there is no “Department of Mathematics and Astronomy” at CSU. OK, there is a department of Mathematics, but any astronomy courses are under the Department of Physics at the College of Natural Sciences.

It seems there is a Pierre Auger Observatory that has some support from CSU but apparently it is located in Argentina.
