The blaze was 25 percent contained. It is now known that the fire was started by people. To block the fire, firefighters are utilizing "dozer lines", which stop the fire from burning with dirt paths.
But, they said it is also in response to increasing fire danger, which has led to several large wildfire incidents. Those living around the northern perimeter of the fire down to Rattlesnake Road were able to return home on Monday, Curry said. Crews are actively working to secure unburned fuel within the perimeter of the fire and mop up heat close to the structures in the community. There were no additional evacuations on Monday.
The Mammoth Fire north of Shoshone has been re-mapped at an estimated 50,182 acres. So Curry says it's not moving almost as fast as it has been. Great Basin Team 6 is made up of experts from various fields including Fire Behavior, Meteorology, Fire Operations and others.
Almost 400 firefighters have been assigned to the fire, with many resources focused on building fire lines to protect structures.
"With the Forest Service or BLM-developed recreation sites, it would be okay to have a campfire in those, but not out in the woods or out on the public lands or even state and private lands an open flame that's not going to be allowed", Callihan said.
Multiple short-duration outages were reported in Lincoln County over the weekend because of the fire, Idaho Power Co. spokeswoman Stephanie McCurdy said.
The fire burned 35,737 acres in Gooding, Lincoln and Jerome counties.
The BLM said the fire was human-caused, but no further details have been released as authorities investigate.
Officials say it has not only affected reservation land, but also the Caribou-Targhee National Forest, Bureau of Land Management and Idaho Department of Lands property.
They also prohibit smoking, except within an enclosed vehicle, building or designated recreation site, or while stopped in an area at least three feet in diameter that is barren or cleared of all flammable materials.
The blaze caused the air quality in Pocatello to be declared "very unhealthy" early Sunday morning. The Idaho Department of Environmental Quality issued the alert for Tuesday because smoke from regional wildfires has caused an increase in particulate matter and ozone levels, and it will remain in effect until conditions have significantly improved, according to a DEQ press release. It had gone up to "moderate" by Monday evening.
