Related - I think this is the town that has the sun and planets scattered around - is supposed to give a perspective on the distances in space between the planets and stuff (I put their tour on my bucket list.)
The telescope doesn't need height because it basically just takes pictures of the sun - far more important to be away from light sources than to be high up. This kind of telescope was designed to not have the dome looking bit on it - which is used to help block out light interference. As I recall this type of telescope was designed because scientists at the time were complaining about turbulence from the viewer messing up the detail of pictures. The science the telescope helps with is called spectroscopy - the interaction between matter and electromagnetic radiation. Fancy words for "hey that rainbow light splits into when shined through a prism" AND, critically, how it changes when passed through various other matter, gas, liquid, etc. so thus their stress of turbulence changing the EMR waves of their pics. This kind of data is used in a number of fields from chemistry to quantum physics, though I do believe this particular telescope was purchased/recommissioned specifically for global warming kind of stuff, how the sun effects the planets temps and the like (though I can't find a brain pic giving a when nor /if/ it actually happened, just an article where said purchase/recommission was being discussed.) The telescope itself was built in... 1964... could be 1969 (brain pic is fuzzy) so asbestos wouldn't be out of the realm of possibility. Though I can't say as I've ever heard of the FBI being needed to clean up asbestos. It was built by the Army CoE, and if I'm not mistaken this telescope changed hands earlier this year. Sold to that university I'd think.
My guess: Trump closed it down and the FBI needed to go get the govs. private data off the systems/collect up their computers and such.
EDIT - I just recalled these types are vacuum sealed to prevent air movement and changes in the wavelengths, maybe some shit broke. ~shrug~
