Stand 4 - Post Point

Submitted by Anonymous (not verified) on

Post received Clayton's note but could not help. The Ranger withdrew up the hill to the timberline and safety. Bert Sullivan took the lead while Post and Tyrrell brought up the rear.

The spot fire consumed the fuels above Post's crew cutting off their escape to timberline, thus making Post Point the men's best chance for survival. Five men panicked and ran downhill through the fire. Of these five, only one would survive. Post, Tyrrell, and Sullivan made every attempt possible to keep the men in place.  Of the 37 who stayed at Post Point, only 3 would perish.

Even with limited technology in 1937, there was an aerial reconnaissance flight that had identified spots along Trail Ridge and higher up on top of the mountain. The recon flight personnel never noticed a spot developing in the bottom of Clayton Gulch below the crews building line.

Given the fire's origin was a tree struck by lightning, could this passing storm have produced more than one strike in the area? If so, could the strike have remained undetected until winds were in alignment to increase the fire behavior? Previous winds were from the southwest and the spot is sheltered from these winds in the bottom of the drainage below. The passage of a dry cold front switched the winds to the northwest.

When dealing with spots, typically one looks in the predominate direction of the wind as to where they might be found (e.g., downwind). The documentation of the event describes the spots on Trail Ridge as within 100 feet of the main perimeter. One probably wasn't looking one-quarter to one-half mile away for a spot.

Today as we fight fire in lightning-prone areas, are we looking for the sleeper that may be established in a site that could, given optimal conditions, come to life in a hurry and cause a similar situation?

Paul Tyrrell knocked down some of the panicked men and lay down on top of them as a human shield to protect them from the fire behavior. A few days later, Paul's severe burns take his life; he passed away at 1300 on August 26, 1937.

Given the fire progression (see Map D above) and the general wind speeds/direction, the likelihood that the fire cast a spot more than a quarter of a mile perpendicular to the major runs during the evening of August 20 and the following morning would be minimal. This was modeled using fire behavior software BehavePlus. This combined with the fact that the spot was not noticed by aerial reconnaissance might lead one to propose the hypothesis that the "spot" wasn't a true spot but a holdover lightning strike. The significance of the difference between a spot and a holdover lightning strike is that firefighters, even today, typically look for spots either close to the fireline and/or downwind in the direction of the smoke column. Burning embers typically are found in the direction of the smoke column. A holdover lightning strike could be anywhere - in this case, below the existing fireline and most likely out of the path of any smoke column from the previous 24 hours.

The fire rushed uphill from the spot in two waves. The group on the ridge top tried to move around to avoid the flame fronts (see Map D above), but there was little room on the ridge. One of the survivors was quoted as saying, "Anywhere you moved, the flames and heat could get to you."

Fire behavior specialist A.A. Brown completed the fire behavior report for the Blackwater Fire. Mr. Brown identified the following factors as key to the blowup:

  1. The ragged edge of the fire.
  2. Underburning of surface fuels that pre-heated the canopy crown.
  3. The heavy fuel model that the fire burned in - today's fuel model 10.
  4. Undetected spot fires.

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.

Date: June 2, 2025
Questions?  Please contact:
Equipment Technology Committee

The Equipment Technology Committee issued Equipment Bulletin: 25-002 to address a manufacturing nonconformity affecting Forest Service specification, 6170-4K Chain Saw Chaps. The issue applies to chaps manufactured in 2024 and 2025 and distributed through FedMall. These chaps may have incorrectly bound edges that expose inner protective layers.

Independent purchasers should inspect all chain saw chaps received from FedMall beginning in 2024, prior to use. Review the full Equipment Bulletin: 25-002 for inspection criteria and recommended actions.
