The wildfire on the northwest slopes of the San Francisco Peaks that charred 100 acres Monday took out a family's vacation cabin, an outhouse, and perhaps an old collapsed structure.

It's the first time a wildfire partly on the Coconino National Forest has burned any structures since the Oak Creek Village wildfires in 2006, though the destroyed cabin was located on private land.

The wildfire is believed to have started from an escaped campfire on private land and was located near the White Horse Hills, three miles east Highway 180.

Dusty Rhodes, who lives near Lake Pleasant, and his family drove up to check on their family vacation cabin and were unsure whether it would be standing.

The cabin was burned entirely down to the foundation, along with a nearby outhouse.

Another old collapsed structure on other land may have burned as well.

Rhodes had the cabin for seven years, along with relatives Randy and Trish Vogel.

"We've owned the place for a good long while, and it was always a scare of ours," Rhodes said of a wildfire.

He was thankful that the trees nearby were not consumed in the fire.

"Heck, you know, 'things could be worse' is what we're trying to say to ourselves right now," Rhodes said.

He went to school in Flagstaff, has other ties to northern Arizona, and plans to rebuild.

The fire was reported at 70 percent contained on Tuesday afternoon, with 50 personnel, two engines and two water tenders reinforcing containment lines and extinguishing fire.

The most recent year during which any homes were lost to forest fire on the Coconino National Forest or Flagstaff area was the summer of 2006, which brought wildfires in Oak Creek Canyon, evacuations along Woody Mountain Road, and cost residential structures in the Village of Oak Creek.

The cause of this fire is under investigation, but a campfire is suspected.

The Coconino County Sheriff's Office is seeking anyone with information about people or vehicles in the area of Potato Flats or Potato Tank on Sunday, and asking those with information to call 774-4523.
