Bone Wars
Although he was employed by Marsh, Lakes was visited by Marsh's "Bone Wars" opponent Edward Drinker Cope, while working at Como Bluff. Although it was the last thing he intended, Lakes was the cause of increased animosity between Cope and Marsh, by co-operating with both. Lakes made the original discovery of the fossils in the formation of the Dinosaur Ridge near Morrison, Colorado. Lakes also drilled several test oil wells in the Golden and Morrison area, however they were not successful producing wells.
