Interesting website from the Boulder, Colorado Jaycees, with information on their saving of the Boulder depot. It had to be moved some years ago due to highway construction, but was saved. Built in the 1880s, it served the Union Pacific originally, then the Colorado & Southern, as well as the narrow gauge Colorado & Northwestern. As passenger trains had to back up the street to get to it, it was replaced with a newer boxlike structure near the mainline in the 1950s.
