Earthquake Information:
Fitzpatrick (1974, p. 26-27) recounted a description of an earthquake in Lily Park, Moffat County in October of 1871 as follows: The “hunters’ moon” of early October [1871] had come and waned; Suddenly, this deep silence was shattered by the most deafening roar, and rumble, and hiss and bellow that mortal ears ever heard. At the same moment the earth beneath shuttered, heaved, rose, fell as if in mortal agony. The towering cliffs of the canyon walls sent loosened boulders in torrents. The spot where the terrified man crouched, a tiny atom of life in the midst of the awful powers of the upheaval of nature, was in the path of the devastating avalanche of rock, yet the man was unharmed and presently the final rolling stone came to a stop and the silence following the earthquake closed in like some physical thing pressing from all sides. Not knowing what moment another shock might come, Wallihan endured the night that seemed as long as eternity. A maximum intensity of VI is assigned to this felt report. The date of this October event is poorly constrained, and it is possible that this earthquake and the following event on November 9, 1871 were actually the same event. If the felt reports from Moffat County and the Georgetown-Central City area are from the same earthquake, then the felt area for this earthquake would be fairly large.
