Fire crews are busy Thursday morning at Palisade High School.

Around 4:30 a.m., KJCT News 8 got reports of what authorities are calling a fully working fire. The blaze is at one of the outside buildings at the high school.

We're told the fire is west of the baseball diamond and south of Palisade High School's football field and parking lot.

Christy McGee with Mesa County Valley School District 51 tells us the fire will not interrupt their day or services to students. They're working to assess damage and at this time don't know when it started or the cause.
