Part III – South Canyon Fire, Colorado, 1994 (A Four-Part Series)

This Day in History is a brief summary of a powerful learning opportunity and is not intended to second guess or be judgmental of decisions and actions. Put yourself in the following situation as if you do not know the outcome. What are the conditions? What are you thinking? What are YOU doing?

Incident Summary:

On July 2, 1994, seven miles west of Glenwood Springs, Colo., lightning ignites a fire in piñon-pine and juniper on a ridge at the base of Storm King Mountain. The entire general area, in a one-year drought, is experiencing low humidities and record-high temperatures. Over the next two days, the South Canyon Fire increases in size. Initial attack resources are assigned. Four days later, on July 6, a dry cold front moves into the fire area. As winds and fire activity increases, the fire makes several rapid runs. Fourteen firefighters perish as they try to outrun the flames.

July 5 – Summary of Activities:

Red flag warnings and very high to extreme fire danger are predicted again today.

A crew of seven firefighters hikes up into the South Canyon Fire at the base of Storm King Mountain. They cut Helispot 1 and begin direct fireline construction downhill along the fire’s edge below this helispot.

The IC orders another district engine crew, one helicopter, and one 20-person hand crew. A load of eight smokejumpers is then substituted for the hand crew.

To support fireline construction, an air tanker retardant drop is requested. After the first load is dropped, due to steep terrain and gusty winds, the IC and pilot agree that more drops would be ineffective.

At 5:30 p.m. the IC and engine crew leave the fire to refurbish equipment. Fifteen minutes later, 8 smokejumpers are dropped at the top of the fire. The IC directs them to work on the fireline from the helispot downhill toward the west drainage.

The Jumper-in-Charge informs the IC that the fire has crossed their fireline and is burning actively. The jumpers begin building fireline on the east side of the ridge.  After sizing-up the current fire, the Jumper-in-Charge orders two Type 1 hand crews. By 10 p.m., the fire has grown 20 acres today. It now covers 50 acres.

Discussion Points:

Downhill fireline construction is hazardous in steep terrain, fast-burning fuels, and rapidly changing weather. Downhill fireline construction should not be attempted unless there is no tactical alternative.

If your fire crew was assigned to construct fireline downhill on Storm King, what would your concerns be? Could you perform this operation safely? (Reference page 1, 6 and 8 in your IRPG for this discussion.)

ETC Equipment Bulletin: 25-003 Flame-Resistant Shirt Survey

Date: June 12, 2025
Questions?  Please contact:
Equipment Technology Committee

The U.S. Forest Service National Technology and Development Program (NTDP) is seeking input on the Forest Service-designed flame-resistant (FR) shirt, currently available through the National Interagency Support Cache system and FedMall.

NTDP is conducting a product review to improve future FR shirt designs. As part of this effort, a short survey is now open for federal employees who have worn any of three recent FR shirt models. Feedback will guide design improvements to better meet the needs of wildland firefighters.

To comply with the Paperwork Reduction Act, responses are limited to federal employees. The survey is open through September 12, 2025.

EMC Memo 25-001: Interim Rapid Extraction Module (REMS) Training and Qualification Requirements

Date: June 3, 2025
Questions?  Please contact:
Emergency Medical Committee

The Emergency Medical Committee has issued interim guidance for Rapid Extraction Module Support (REMS) teams. Until further notice, Type I and II REMS teams must designate a team leader qualified at Firefighter Type 1 Squad Boss (FFT1) or higher. This temporary change replaces the Single Resource Boss (SRB) requirement, which is currently not feasible due to administrative barriers.

This memorandum does not include any other changes to the NWCG Standards for Rapid Extraction Module Support, PMS 552. This interim change takes effect immediately and will remain in place until further notice.
