Haystack Fire Daily Update for September 22Image options: [ Full Size ]

The Dillon Interagency Dispatch received a report of a possible fire start near Haystack Mountain to the east of I-15 between the communities of Butte and Basin on July 31, 2021. Helicopters provided bucket drops in the fire area. Agency administrators and fire leadership initially determined the area to be unsafe for ground crews due to large boulders, steep slopes, a large number of snags, difficult terrain, and no safe locations to insert or extract crews.

On September 6, the fire spotted into a continuous pocket of timber to the east near Little Boulder Park. Crews at this time began taking actions to protect private in-holdings and structures in the area. Crews are now able to safely engage the fire from the ground and are being supported by aircraft.

Great Basin Team 4 assumed command of the fire on September 22.

Fuels Involved

Timber (litter and understory) and brush (2 feet). Significant mountain pine beetle mortality in lodgepole pine from a 20 year old epidemic has created significant dead and downed pockets primarily in the upper elevations. Mid elevations are a mix of nearly pure Douglas-fir and pockets of mixed conifer with a brush understory. Many areas have large granitic boulders with both dead and live (mostly cured at this point in the year) fuels. Lower elevations transition to areas of heavily grazed grass/sage and pockets of Douglas-fir and juniper which transition into nearly completely grass fuels on the valley bottom.

Significant Events

Moderate fire behavior with creeping, isolated torching and group torching. The main activity occurred on the northeast portion of the fire with single and group tree torching being the

main cause of growth.

Outlook

Planned Actions

Crews will continue to implement structure protection measures on the outskirts of Boulder. Strategic burn-out operations

on the north and east flanks are planned to continue if weather and fuel conditions allow. Crews will monitor fire growth towards Elk Park, prep line on the west/northwest flank and assess structure protection needs.

Projected Incident Activity

Pockets of dead/down lodgepole pine will continue actively burning with single and group tree torching in isolated pockets overnight with smoldering and creeping on the majority of the fire.

In the next 24 hours, lighter winds are expected but unseasonably warm and dry conditions with marginal overnight recovery will produce potential for the fire to become more active. Significant increase in growth is unlikely due to lack of winds. Burnout operations are planned which will increase

acreage and fire activity as well.

No significant wind events are forecast in the next 72 hours, however, multiple days of poor humidity recovery and warm/dry conditions will result in increased fire activity daily.

Current Weather

Weather Concerns

Today cloud cover decreased by afternoon allowing afternoon

sunshine. Humidity minimums stayed above 30%. Breezy

northwest winds developed in the afternoon (10 to 15 mph). Friday

will be drier and warmer with light winds and stable airmass.

Saturday sees even warmer conditions and stronger winds.
