Who to contact if an impact crater has been found?

“Someone contacted me about finding a meteorite impact 
crater and wants to know who to contact to get it verified 
and then get credited for his find. He didn’t say if he found 
any meteorites around/in it.  Any ideas of who he should 
contact?  He said it’s in Colorado.’

In addition to the Denver Museum of Nature and Science,
he can also contact the Colorado Geological Survey at:

The local state geologists are well qualified for providing
opinions about potential meteorite impact craters. One of
their (geologic) mapping geologists would be the best 
person to contact.
