Eldorado Springs and the southern reaches of Boulder meet the high front range in this mid-1960s survey, updated in the early 1970s to show urban expansion. The landscape transitions from the institutional corridors of the National Bureau of Standards and the National Center for Atmospheric Research in the north to the industrial-age infrastructure of the Denver and Rio Grande Western railroad winding through the south.
