Despite the efforts of over a thousand firefighters, the 513,437-acre Big Grass fire grew by over 70,000 acres, pushing it even closer to being the largest wildfire in Oregon history.
The current record holder — the 2012 Long Draw Fire — clocked in at 557,028 acres and burned into Nevada.
Like that fire, the Big Grass fire is also a border-spanning blaze, with at least half of the fire stretching into Idaho. As of Sunday morning, the fire was at 39% containment, federal data showed.
Across the state, 30 other fires were burning in Oregon, with several qualifying as “mega wildfires,” which are incidents that exceed 100,000 acres. The 308,000-acre Coleman Creek and 105,000-acre Second Flat Fire, as well as the 200,000-acre Hay Creek and Rowe Creek complexes all qualify as megafires.
Firefighters made large gains in containing each of those fires in the last week, and as of Sunday morning all of them were between 79% and 97% contained, federal data showed.
Closer to Portland, the 54,000-acre Grasshopper fire in Mount Hood National Forest continued to threaten structures and prompt evacuations as it grows, federal data showed.
Oregon Air National Guard troops joined the firefighting mission on Mount Hood this weekend, the Oregon Military Department said in a statement, and on Saturday they worked to wrap structures in fire-proof material. And starting Sunday, troops took part in watching and maintaining the firelines around the fire’s perimeter.
As of Sunday morning, it sat at 23% containment.
