Rocky Mountain Area Complex Incident Management Team 3
When you hear the word “FOBS” in the wildland fire world, what exactly does that stand for and what does it mean? A field observer (FOBS) is someone who is responsible for collecting incident status information and providing those findings to other groups in the incident command system.
In this video, field observer Ryan Ricke explains more about his responsibilities and what his role has been on the Derby Fire. #derbyfire#FireYear2025
Derby Fire Update – September 1, 2025 Rocky Mountain Area Complex Incident Management Team 3 Casey Cheesbrough, Jay Miller, Ben Sanders Incident Commanders Fire Information: 970-355-3283
Size: 5,475 acres Containment:Â 6% Total personnel: 578 Cause: Lightning Resources: 4 aircraft, 9 hand crews, 27 engines, 12 heavy equipment
Current situation:
A spike camp is located near West Fork Red Dirt Creek, east of the fire edge, allowing hotshot crews to reduce travel time to where they are building direct line on the fire’s edge. The hotshots are working south to eventually meet crews working up from Poison Creek on the southeast corner. This assignment may take several days to complete.
A combined group of 30 hotshots and highly skilled medical personnel will return by helicopter to the Hack Lake area to continue their work on the western perimeter. Being transported by helicopter allows the crew to save time and conserve energy for the day’s task, rather than making an arduous hike to the fireline. An Unmanned Aerial System (UAS) will scout for areas of heat in spots outside the perimeter in the northwest portion of the fire and south of the Flat Top Wilderness area. UAS reconnaissance flights identify areas of heat providing crews with coordinates to effectively locate them.
Firefighters continue backhauling excess structure protection equipment from areas where it is no longer needed. Crews continue to patrol and monitor the southern portion of the fire, searching out areas of heat and extinguishing them as they work towards containment. Crews will also monitor and maintain structure protection systems that remain along the Sweetwater, Sheep Creek, and Red Dirt Creek roads.
Weather and fire behavior:
Smoke levels are expected to be more noticeable than in previous days as the drying trend continues. Starting Monday, fire activity will increase with rising temperatures and lowering humidity, as seasonal warm and dry pattern returns to Western Colorado this week. Temperatures will stay in the low seventies with a mild 10 miles per hour wind.
Evacuations and closures: Fire restrictions and closures remain in place for lands within the Bureau of Land Management – Colorado River Valley Field Office areas, https://www.blm.gov/ucr-fire-restrictions. Restrictions and closures remain in the White River National Forest. See Critical and Fire Restriction Forest Alerts at https://www.fs.usda.gov/r02/whiteriver/alerts/ .

Actualización Diaria para el Incendio Derby – el 1 de septiembre de 2025
Equipo 3 del Manejo de Incidentes Complejos del Ãrea de las Montañas RocosasÂ
Comandantes del Incidente: Casey Cheesbrough, Jay Miller, Ben Sanders Información del incendio: 970-355-3283
Un campamento secundario se encuentra cerca de West Fork Red Dirt Creek, al este del borde del incendio, lo que permite a los equipos de bomberos “hotshot†(bomberos forestales altamente capacitados y especializados) reducir el tiempo de viaje hasta donde construyen una lÃnea directa en el borde del incendio. Los bomberos trabajan hacia el sur para reunirse con los equipos que trabajan desde Poison Creek en la esquina sureste. Esta tarea podrÃa tardar varios dÃas.
Se espera que los niveles de humo sean más visibles que en dÃas anteriores a medida que continúa la tendencia a la sequÃa. A partir del lunes, la actividad de los incendios aumentará con el aumento de las temperaturas y la disminución de la humedad, ya que el patrón estacional cálido y seco regresa al oeste de Colorado esta semana. Las temperaturas se mantendrán alrededor de los 70°F con vientos suaves de 10mph.
Evacuaciones y cierres: Las restricciones y cierres por incendios se permanecen vigentes en los terrenos bajo la administración de la Oficina de Administración de Tierras del Valle del RÃo Colorado: https://www.blm.gov/ucr-fire-restrictions.

Ops Update Monday morning, Sept. 1, 2025, Ryan Sharpe, Operations Sections Chief, discusses firefighting tactics on the #DerbyFire.
Firefighters are performing multiple operations today. A spike camp located near West Fork Red Dirt Creek has been set up east of the fire edge allowing hotshots to reduce travel time to where they are working direct on the fire perimeter. A group of hotshots will also return by helicopter to the Hack Lake area to continue their work on the western perimeter. Firefighters continue backhauling excess structure protection equipment from areas where it is no longer needed.
The FDNY Incident Management Team sincerely thanks the Meeker community, as well as the firefighters, contractors, and partner agencies who worked tirelessly on the Lee Fire. Thanks to their dedication and resilience, the fire is now 99% contained.
It has been an honor to serve alongside you during this time. The progress made is a direct reflection of the hard work of so many people coming together in a time of need. We leave grateful for the welcome we received and for the opportunity to stand with this community.
Ryan Sharpe, Operations Sections Chief, discusses firefighting tactics on the #DerbyFire. Firefighters are taking advantage of current weather conditions ahead of a warming and drying weather trend that begins today, Sunday, August 31.
A spike camp has been set up on the east side of the fire. A spike camp is a temporary satellite camp located closer to the fireline – crews will sleep overnight in this location to reduce their travel time to reach the fireline and increase their daily work time. These firefighters are constructing fireline along the eastern edge of the fire moving south.
Crews will be flown in to construct fireline on the west side of the fire today, along with a Rapid Extraction Module Support (REMS) team who can provide highly-skilled medical care in the event of an emergency.
On the south side of the fire, from Sugarloaf Lake moving south, crews continue to improve the fireline. Mop-up and patrol continues along the southern fireline. On the southeast side of the fire, firefighters are constructing line moving north along the eastern fire edge – they will eventually meet up with the firefighters working their way south along the eastern fire edge.
The structure protection firefighters are beginning to backhaul equipment and supplies that are no longer needed in the Sweetwater area due to reduced fire behavior. Initial attack resources have been indentified to respond to any new fire starts within the Temporary Flight Restriction area (TFR) of the #DerbyFire.
Fire Information: 970-355-3283 Size: 5,749 acres Total Personnel: 699 Containment: 6% Cause: Lightning Resources: 4 Aircraft | 14 Hand Crews | 36 Engines | 17 Heavy Equipment
Current Situation: Firefighters are working directly along the fire’s edge to take advantage of moderated fire activity ahead of an upcoming warming trend. Crews advanced handline construction on the southwest corner of the fire Saturday. To have them closer to their work area, a hotshot crew will be flown into the area Sunday with a REMS (Rapid Extraction Module Support team). This is a specialized team that can provide a high-level of medical care and rapid extraction if needed. An Unmanned Aerial System will help support firefighters by scouting for heat in the area and to alert them of safety hazards.
Crews continue to construct indirect handline on the eastern perimeter of the fire, moving north. They are evaluating hand line construction options closer to the fire’s edge, as well as looking for potential helicopter medivac spots to support the ability to work in the steep terrain. This area has a higher concentration of mixed conifer and subalpine fir trees. Heat remains in the dead and downed timber. Fire weakened trees in this area can pose a threat to firefighter safety. Falling snags are a common hazard on the fireline.
The structure protection crews are monitoring fire defenses along Sweetwater, Sheep Creek, and Red Dirt Creek roads. Firefighters are beginning to remove hose lays, pumps and sprinklers around structures in Sweetwater Valley closer to the Colorado River corridor where the fire threat has lessened. Initial attack resources have been identified among the structure protection crew to respond to assist local resources with any new fire starts that occur within the Temporary Flight Restriction (TFR) area of the Derby Fire.
Weather & Fire Behavior: Sunday will be the beginning of a warmer and dryer trend in the area. There is also a limited chance of precipitation with slight winds. Humidity will dip into the 20% range, which can result in grass, pine needles, twigs, and other light fuels to lose moisture and increase fire activity. Expect more smoldering and creeping of the fire due to the drier, warmer weather.
Evacuations and Closures: Fire restrictions and closures remain in place for lands within the Bureau of Land Management – Colorado River Valley Field Office areas and White River National Forest.

Total acreages: 5,749 acres 6% containment 699 personnel
Building fireline takes all kinds of kinds. On the southeast side of the fire, crews continue to strengthen the fireline and gradually move north along the eastern side. Multiple handcrews and a variety of heavy equipment are working together to advance the fireline.
Taskforce leaders and heavy equipment bosses help coordinate this work. Medical personnel accompany firefighters to keep everyone safe. A field observer follows the progress of the fireline and collects information on the fuels, fire behavior, and on-site weather. #DerbyFire#FireYear2025

Location: 11 miles south of Meeker, Colorado Start Date: 08/02/2025 Cause: Lightning Size: Lee Fire: 137,758 acres Containment: Lee Fire: 95% 179 Total Personnel; 2 Hand Crews; 2 Dozers
KEY MESSAGE This is the final daily update from the FDNY Incident Management Team. On Monday morning at 0600, command of the fire will transition back to local agencies.
Over the past week, our team has been honored to serve alongside local, state, and federal partners in support of the Lee Fire. We are grateful for the cooperation, resilience, and support shown by the community and those working on the ground. As we prepare to return home, we do so with confidence in both the progress made and the agencies continuing this important work.
CURRENT STATUS Crews have now expanded suppression repair into additional areas of the fire, focusing on debris removal and restoration work. These projects are being completed in close coordination with Resource Advisors to ensure agency standards are met and to lay the groundwork for long-term recovery of the landscape.
WEATHER AND FIRE BEHAVIOR Clear skies and warming temperatures are expected today, accompanied by lower humidity. While the overall forecast points to mild and favorable conditions, there remains a chance for an isolated shower or thunderstorm this afternoon. Any storm activity could bring gusty winds up to 25 mph, which may briefly impact ongoing suppression repair. Looking ahead, the return to drier weather will allow crews to continue making steady progress across the fire area.

Fire Information: 970-355-3283 Office Hours: 8 a.m. to 8 p.m.
Size: 5,738 acres Total Personnel: 667 Containment: 6% Cause: Lightning Resources: 4 Aircraft | 16 Hand Crews | 36 Engines | 17 Heavy Equipment
Current Situation: Containment increased slightly on the south, west of East Fork Sheep Road. This is where interior heat has decreased, and wind and weather conditions are unlikely to push the fire over the control line. Firefighters continue to patrol, mop up, and extinguish hotspots along the southern control line. Hotshot crews continue to construct fireline along the fire edge on the western side as they progress to the north. Handline construction is progressing on the east side of the fire, extending northward from an existing dozer line. Air resources are evaluating proposed medical evacuation helispots as the firefighters move into more rugged, remote terrain. An Unmanned Aircraft System is also available to help assess fuels, fire behavior and areas of heat using an infrared camera. Structure protection crews are actively monitoring and maintaining defenses around more than 500 structures along Sweetwater Valley, Sheep Creek, and Red Dirt Creek Road.
Weather & Fire Behavior: Recent rainfall has kept relative humidity levels high, helping to minimize fire behavior. Saturday will see slowly clearing skies and sunshine with a slight possibility of rain at higher elevation. A gradual warming and drying trend are expected to begin on Sunday. Relative humidities will start to drop a little each day, however, a few days of drying will be needed before any significant increase in fire activity is likely. Interior heat pockets may continue to produce smoke where dead and downed trees are still smoldering. Fire may slowly creep along the ground in areas where mixed conifer, subalpine fir and lodgepole pine trees transition into aspen stands.
Evacuations and Closures: Fire restrictions and closures remain in place for lands within the Bureau of Land Management – Colorado River Valley Field Office areas and White River National Forest.

Clima y el comportamiento del fuego: Las lluvias recientes han mantenido altos los niveles de humedad relativa, lo que ha ayudado a minimizar el riesgo de incendio. El sábado se despejará lentamente el cielo y habrá sol, con una ligera probabilidad de lluvia en zonas de mayor altitud. Se espera que el domingo comience una tendencia gradual de calentamiento y sequÃa. La humedad relativa comenzará a descender ligeramente cada dÃa; sin embargo, se necesitarán algunos dÃas de sequÃa antes de que sea probable un aumento significativo de la actividad del incendio. Es posible que las bolsas de calor interiores sigan produciendo humo donde los árboles muertos y caÃdos aún arden lentamente. El fuego podrÃa extenderse lentamente por el suelo en zonas donde las conÃferas mixtas, los abetos subalpinos y los pinos contortos se transforman en álamos.
Evacuaciones y cierres: Las restricciones y cierres por incendios se permanecen vigentes en los terrenos bajo la administración de la Oficina de Administración de Tierras del Valle del RÃo Colorado y el Bosque Nacional White River.
