Overlaying map against map doesn't quite add up. Your map also points the Denver DUMB to a quake that happened in an entirely different part of Colorado.. hopefully more evidence surfaces.
Of course I get the idea. It'd be wonderful to have an -actual map- to compare to to track this. Maybe we'll get confirmation at some point in the future, but pointing out quake areas (some that have only become more common since fracking began) in the vicinity of some hand old drawn map does not necessarily equate to DUMBs being destroyed.
