On Friday, the Contreras Fire damaged several buildings at Kitt Peak National Observatory National Science Foundation’s NoirLab (National Optical-Infrared Astronomy Research Laboratory) said in a release.

“All material scientific observatory structures are still standing and there appears to be very little external damage at this time in terms of facilities on the Southwest Ridge, although many non-science buildings were lost,” Noirlab said.

According to InciWeb, the fire is burning in highly flammable grass and steep, rough terrain that is difficult to brush.

Inciweb says the fire started on a remote ridge of a mountain range on the Tohono O’odham Indian Reservation on June 11. It lists the cause as lightning.
