red rock coulee

Red Rock Coulee is a barren field in Canada that looks like it has objects from outer space

Mars might be a little tricky to travel to, but you can always visit the Red Rock Coulee — a mysterious, barren field in Alberta dotted with otherwordly rocks.

The spherical red boulders measure over eight feet across, making them some of the largest sandstone concretions anywhere in the world.

The geological oddities date back to the prehistoric era, and you can still see where the sea once surrounded the rocks by looking at the unique rings in the boulders.

Over millions of years, the iron in the rocks oxidized, giving them their distinctive red color.

The Red Rock Coulee is located about 50 kilometers southwest of Medicine Hat, and the remote location only adds to the otherwordly beauty of the boulders.

Climb over the uniquely round spheres, or pause to admire the boulder that's split in half, revealing its strange shape.

Alberta has some of the most beautiful sunsets in Canada, so be sure to visit Red Rock Coulee just before dark for some truly epic photos.
