Watford City in McKenzie County, North Dakota — The American Midwest (Upper Plains)
Edge of a Glacier
These small boulders are clues to a fascinating story. Geologists believe they were ripped from bedrock 400 miles north in Canada and carried to this point by a great glacier which covered nearly all North America north and east of here.
The ice melted thousands of years ago, but these rocks, called “erratics” because they are “out of place”, are clear evidence the glacier once covered the ground upon which you stand.
The course of the Little Missouri and Missouri Rivers from here east marks the southern edge of the glacier that dropped these rocks.
