They are found in the upper Midwest of the United States.

The earliest effigy mounds created in the shape of animals could be up to 3,000 years old.

It is estimated that up to 20,000 effigy mounds were created just in Wisconsin.

The mound builders suddenly stopped creating them due to a sudden volcano eruption

Answer 1

The fact that is NOT correct is:

"The mound builders suddenly stopped creating them due to a sudden volcano eruption."

There is no evidence to suggest that effigy mound builders ceased their activities due to a volcanic eruption. Effigy mounds in North America were primarily built by Indigenous peoples and their decline is generally attributed to a variety of social, environmental, and cultural changes rather than a single catastrophic event like a volcanic eruption.
