Hailing from the town of New Brighton — a suburb just outside Minneapolis and St. Paul — the Bartz brothers have spent the last four winters creating larger-than-life snow sculptures depicting creatures from under (or near) the sea.

Minnesota isn't known for its oceanic wildlife, but that didn't stop this brotherly trio from using their imaginations.

Ever since their very first major snow sculpture in 2012 (a pufferfish), they've been ramping up their skills every year. In return, the crowds and attention keep getting larger.

Their 2015 masterpiece, a sea turtle, was completed Jan. 7 after several weeks of hard work.

The spectacle quickly went viral, and it wasn't long before this ambitious creation made an appearance on the "Today" show as well as the Facebook trending box. You can watch the entire building process for the sea turtle sculpture in the video below:
