Delton Kellogg schools, as a result, will be closed Monday. The schools’ buses are running starting at 9:30 a.m. Teachers will be riding the vehicles to make sure that a parent or guardian is at home with idle students. The children will not be allowed to leave without a parent or supervisor.

The Delton District Library also announced that it closed Monday due to the fire.

Local fire officials said it is not clear what caused the fire.
