The Sulphur Fire, started by lightning, was reported on August 15th. This fire is located across the river from Mud Volcano, more than a mile from the road, and is visible at times. The fire is currently estimated at 5 acres. The fire is being closely monitored throughout the day.

Update - 24 Aug - Fri

The Sulphur fire continues to spread slowly through surface fuels. Heavier continuous fuels exist to the north/northeast, but the fire will have a hard time getting there under current rates of spread. The fire will be manned by two monitors who will GPS the perimeter. It is estimated to be 6 acres in size and managed for resource benefits.

Update - 25 Aug - Sat

Extreme heat build-up was again observed in the ground fuels as the fire made an upslope run to the east along the south flank. Short-duration crown fire was observed beginning about 4:00 pm. The fire is spotting ahead of itself, and these spots will probably get active tomorrow and continue upslope in an easterly direction. The fire was mapped at 42 acres and is being managed for resource benefit.

Update - 26 Aug - Sun

More torching and short-duration crown fire runs were observed, although direction of spread shifted from directly east to southeast in response to west/northwest winds. The head of the fire has gotten progressively wider as numerous spots ahead of the main fire have burned together. Ground fuels continue to hold the heat in advance of the daily burn period, and jackpiles were actively burning throughout the night. The fire crossed the ridge upslope to the east via spotting very late in the burn period. The fire was mapped in mid-afternoon at 250 acres.

Update - 27 Aug - Mon

Plenty of heat build-up and frequent torching was observed at the head of the fire. Unburned fuels within the perimeter also torched on occasion. The south flank made short-duration crown runs as downdrafts from a passing thunder cell influenced local fire behavior. The fire was mapped at 380 acres.

Update - 28 Aug - Tues

Spread was observed to the north, south, and east. The south flank slowly backed down the slope, while the northeast flank continued to move upslope with short-duration crown runs and spotting. The upslope head of the fire continues to widen, and intense heat is being generated there in the ground fuels. Plenty of unburned fuels remain within the perimeter, which is mapped at 540 acres.

Update - 30 Aug - Thurs

All flanks of the fire were again active today. Fire spread was observed to the northeast, mostly by isolated torching and spotting out ahead. Expansion on the east flank was mostly due to continued backing down slope. The west flank similarly increased by spotting out as well. One spot fire 0.6 miles to the northeast of the main body became active again, but activity was mainly confined to the ground fuels. The fire was mapped at 700 acres, but plenty of unburned fuels remain within the established perimeter.

Update - 3 Sept - Mon

The fire was mapped today at 825 acres, The fire was particularly active on its western flank, where it crossed a drainage with a limited rated of spread. Monitors continued to collect live fuel moisture sampling and observe fire behavior today.

Update - 5 Sept - Wed

Smokes were evident all along the perimeter as well as the interior of the burn. One hotspot on the northwest flank saw the occasional torching tree. The fire remains at 825 acres.
