Unless expressly noted, there are no awards for winning the voting. Our primary focus is to highlight the abilities and accomplishments of all the athletes and teams included in our poll.

3. Mellen Granite Diggers (Wisconsin)

Mellen has a long history as a mining town, especially for a special type of black granite, and its physical mascot is as colorful as they come. It's a blue chipmunk named Chipper who carries a pick-ax.

7. Bryn Mawr Mawrtians (Maryland)

Michigan has the only Martians in the country among U.S. high schools, and Bryn Mawr has the only Mawrtians. Mascot pride is brimming at the 140-year-old Baltimore school.
