At that point, earthquake and ground deformation patterns beneath the summit indicated a small intrusion of magma had occurred.

Changes in seismicity can then be tracked over time and related to data from other geophysical methods like measurements of ground deformation from radar satellites and on-the-ground GNSS receivers.

Diminishing deformation outward from the center, a marginal syncline, and upturned beds on the periphery of the basin are also suggestive of meteor craters.

The report said a March 2021 engineering assessment of Keystone’s pipeline from southern Nebraska to northern Oklahoma showed five bends, including Washington County’s, had the same oval “deformation.”
