KALISPELL, Mont. -

An early morning arson fire destroyed the pole vault mat, runway and uprights at Glacier High School on Tuesday.

Glacier Activities Director Mark Dennehy says the exact cost to repair the damage and replace the equipment is not yet known, but he estimates it will be close to $40,000.

The fire burned the foam pole vault landing mat, damaged the standards and the surface of the runway which sits just beside the running track at Glacier.

The surface of the running track does not appear to be damaged.

With track and field season just getting underway Glacier’s pole vaulters will have to practice at Flathead High School. Glacier’s Lonnie Sherman is the No. 1 ranked high school pole vaulter in the state.

School officials and the Kalispell Police are investigating the arson and say that school’s security cameras have captured images of people on school grounds at the time of the fire. No suspects have been identified yet and anyone with information is asked to contact Flathead Crimestoppers at 752-8477

Glacier High School has announced that they will offer a $1,000 reward in the case.
