The Great Alberta Meteor Impact

The Great Alberta Meteor Impact put that nice curve in the Coast Range of British Columbia
The Great Alberta Meteor Impact was centered at 56°31'48"N, 118°20'46"W . The seismic circles from this impact shown above are at 70, 353, 665, and 990 kilometers radius from the center of impact. This image is linked to a larger image for more detail (4800 x 4800, 3.66M)
