This enormous structure was known about long before Google Maps boosted its popularity. Located in Walsh, Alberta, Canada, this structure is part of a natural land formation in a baron mountain range. This image is that of a woman with a headdress on. Since modern roads penetrated these mountains, it looks like she's wearing earbuds as well.
