After the fall marching band season, all students have the option of joining the Irondale Winterguard. This group is open to any student registered at Irondale or Mounds View High Schools; music membership not required. The winterguard develops an exciting production to taped music, which enables the members to further their Colorguard experience in this unique indoor pageantry art. The winterguard will compete in eight to ten shows during the months of January through late March or early April

Depending on the number of students interested each year, Irondale may open auditions to students from surrounding communities.

The Irondale Winterguard is an activity associated with the North Star Color Guard Circuit in Minnesota and Winter Guard International (WGI) nationally. They were the Scholastic Open division Gold Medalists at the 2002 Winter Guard International (WGI) World Championships!!
