The Boji Mammoths played their inaugural High School Hockey Season in 2016 beginning a new era of opportunity for area high school athletes. The Mammoths currently draw players from Spirit Lake, Okoboji, Lake Park, and Spencer school districts.

The Mammoth's hockey season runs from mid-October through the end of February. In 2022, the Mammoths were the inaugural Iowa High School Hockey Alliance Champs and repeated in 2023! Mammoths will enter into our eighth overall season and third season in the Iowa High School Hockey Alliance for the 2023-2024 season.
