Firefighter Mopping Best of the Lone Rock Fire 2024

The Lone Rock Fire began July 13, 2024, and is currently being managed under a full suppression strategy. Local ranchers and landowners along with local Rural Fire Protection Districts initially responded to the wildfire protecting structures and private property. Multiple Incident Management Teams have been working to contain the fire, protect structures, and other values at risk. Southwest Area Incident Management Team 2 is currently managing the fire after assuming command of the fire from Northwest Team 2 on Wednesday, July 31, 2024, at 6:00 AM. 

Oregon State Fire Marshal's Red Team under Incident Commander Ian Yocum provided critical structure protection day and night during the initial stages. Oregon Department of Forestry personnel continue to work protecting state lands.

Firefighters continue to work on building containment lines. The fire footprint is within the following counties: Gilliam, Wheeler, Morrow and Grant. Hot, dry and windy weather initially hampered firefighter's ability to contain and control this wildfire as it grew to more than 130,000 acres. Wetter conditions allowed firefighters to gain containment and secured the northern end of the fire. Many structures were saved during this wildfire, though unfortunately some were lost. 

 

Evacuation Information:

Only some Level 1 (ready) evacuations remain. Visit the interactive evacuation map for up-to-date changes to evacuation levels: Interactive Evacuation Map

Or visit local county websites for more information: 

 

Shelters:

An evacuation center has been set up at the Wheeler High School (600 E B Street, Fossil, Ore.). A large animal shelter is available at the County Fairgrounds (720 E 3rd Street in Fossil, OR.).

Current Situation
Total Personnel: 189
Size 137,222 Acres
Percent of Perimeter Contained 98%
Estimated Containment Date 08/15/2024
Fuels Involved

Above average grass fuels exist at the northern and southern perimeters of the fire area. The continuous grass crop is cured and readily available for rapid ignition and elevated rates of spread with an ignition source and even moderate wind. Moving up in elevation towards the central area of the fire, grass fuels transition to grass with shrub juniper, shrublands, ponderosa pine on eastern/northern aspects, pine/grass savannas, and finally, at the highest elevations within the Umatilla National Forest, pine with mixed conifer.

  • Timber (Grass Understory)
  • Tall Grass (2 Feet)
  • Timber (Litter and Understory)
Significant Events

No heat sources were detected within 150' of control lines and active patrol and monitoring is continuing. Isolated heat sources continuing to slowly burn out on the interior of the fire including two isolated stumps 1/4 mile south of the FS-21 road in the middle of the fire perimeter. As these heat sources are surrounded by previously burned fuels and over 1.5 miles from the closest containment line, they pose no threat beyond potentially being visible to anyone driving on Road 21.

  • Minimal 
  • Smoldering 
Outlook
Planned Actions

Fire is approaching 100 percent containment. The fire will continue to be patrolled and if smoke is visible and the heat source will threaten the lines it will be mopped up.   

Projected Incident Activity

12 hours:    Minimal smoldering in isolated hot spots well interior of control lines.

24 hours:    A few isolated remaining individual hot spots well interior of control lines. Future growth is unlikely.

48 hours:    Minimal detectable heat remaining and what isolated heat sources remain are interior and are very improbable of creating growing fire activity.

72 hours:    Smoldering only.

Anticipated after 72 hours:    It is likely the majority of remaining isolated heat sources and scattered heat will have consumed all available fuel within further ignition proximity and self-extinguished. 

Remarks

Local landowners continue to actively participate in the suppression actions. Fire liaison officers continue to work directly with ranchers and include them in the operational planning process to obtain local knowledge and coordination. Evacuation levels have reduced. Mixed ownership creates some barriers for operations but the agencies of BLM, USFS & ODF continue to be in alignment and messaging. Additional information can be found on the Lone Rock Facebook page.

Current Weather
Weather Concerns

A weak series of disturbances are passing through the atmosphere in the vicinity of the fire area this weekend bringing a slight decrease in temperature and a marginal increased potential for isolated storms. The primary threat of the current weather pattern is the possibility of dry lightning and the continued dry receptive fuel bed throughout the area.
