This memorial is dedicated to the brave men who perished during the Blackwater Fire of 1937.

The fire started on August 18, 1937, as the result of a passing lightning storm during the late afternoon. The point of origin was traced to a sub-alpine fir located on the west bank of Blackwater Creek approximately four miles from this point.  The Blackwater Canyon is a tributary to the North Fork of the Shoshone River. The canyon is mostly oriented north/south, with the high country at the southern end of the range. The elevation ranges from 6,200 to 11,096 feet with canyon walls rising to rims of decomposing granite. The local winds are out of the southwest; any frontal passages would produce typical wind shift patterns. 

The fire slept through August 19 and came to life the afternoon of August 20, 1937. Men of the Bureau of Public Roads Crew (BPR), the Wapiti Civilian Conservation Corps Crew.

Note: To relieve economic hardships during the great depression in the 1930s the U.S. Government created the Civilian Conservation Corps (CCC). The CCC employed out-of-work young men to help battle the destruction and erosion of our natural resources. These crews were involved in firefighting around the country. Training for firefighting was "very basic" at best. National Civilian Conservation Corps Alumni.

(CCC - Company 1852), and the Lake (Yellowstone NPS) CCC Company arrived at the fire that afternoon and evening. Forest Supervisor Sieker and District Ranger Charlie Fifield, were the men in charge of the fire. They used direct attack tactics, as the strategy was to anchor and flank the fire. The expectation was that the fire would not grow appreciably during the night. However, about midnight the winds increased causing the fire behavior to increase and run up the drainage to the southeast of Trail Ridge. This was a short-lived run, but the fire continued to burn throughout the night. By next morning, the aerial reconnaissance observed the entire drainage was consumed by crown fire behavior with two spot fires between Blind Creek and the drainage to the east. See Map A above.

The firefighter memorial is easily located alongside Highway 14/16/20. It was built by the CCCs and dedicated in 1938. There is a large paved turnout here and a Forest Service parking area below the roadside turnout. The road turn-off to Blackwater Canyon is just east of the memorial site.

This sign along Highway 14/16/20 shows the turnoff to the Blackwater Lodge. This is also the turnoff for FS Road 435 that goes to the upper trailhead in Blackwater Canyon.

FS Road 435 goes south from Highway 14/16/20 and crosses the North Fork of the Shoshone River.

FS Road 435 ends two miles from Highway 14/16/20. This is the upper trailhead, sometimes referred to as Lower Camp. Note the limited parking.

The shift change began along this ridge during the late morning of August 21st. Smoke was hanging in the drainage, and the fire was backing down the north side of Trail Ridge. The Ten Sleep CCC relieved the Wapiti CCC Crew. The Ten Sleep CCC crew had been expected to arrive about 0800 to the base camp but didn't arrive until 1200. The BPR crew and Yellowstone CCC continued to work. Supervision of the suppression activities was transferred from Forest Supervisor Sieker and District Ranger Fifield to District Rangers Urban J. Post and Alfred G. Clayton. Deputy Forest Supervisor Carl Krueger continued to fly air patrol and report the fire's status.

Mr. Krueger reported several spot fires near the fireline at 1240. The spot fires were suppressed as the line was constructed. Krueger didn't identify any spots in the vicinity where the blowup originated. The strategy and tactics were that Ranger Post would take the lead with assistance from Jr. Forester Paul Tyrrell. Ranger Clayton followed to improve the line and catch any new spot fires. As Post and crew hiked the ridge to start work, he was on the lookout for spots over the line and into the next basin. At that time, no spot fires were seen below [see map B]. They were unaware that the relative humidity dropped to 6% with a temperature of 90° down at camp or that a spot was in the bottom one-third of a mile below them; they didn't anticipate afternoon winds. See Map B above.

Note: During the 2003 fire season, the Shoshone National Forest experienced the worst fire season on record with five large fires and 50 total starts. See Map C above.

First distinct switchback in the trail is the suggested location established for Stand 2.

Areas of overlap between the 1937 and 2003 fires can be seen. Notice the older snags evident in the foreground and the recently burned terrain in the background.

In 1937, this area was a stand of mature trees. If you look uphill from where you are standing and visualize the fire creeping downhill, you can see that the fire was out of alignment. During the morning of August 21, the fire had a slight southwest wind. This wind pattern is a typical airflow over Wyoming's Wind River and Absaroka Mountains. At this time, the BPR and Ten Sleep CCC crews were cutting underslung line across the drainage. Firefighters didn't think about using lookouts. Foreman Saban and Junior Assistant Hale from the Wapiti CCC with five or six men from the Ten Sleep CCC enrollees stopped and dammed up the creek to fill backpack pumps. See Map D above.

As Post and his group gained the ridge to the north, they noticed the smoke below Clayton and his group. Clayton also noticed it and prepared to abandon line construction and attack the new smoke. Clayton directed his crew to the gulch to fill their backpack pumps while he headed down hill to scout out the spot in the hole. The last word received from Ranger Clayton was a written note to Ranger Post.

Post,
We are on the ridge in back of you, and I am going across to "spot" in the hole. It looks like it can carry on over ridge east and south of you. If you can send any men please do so since there are only 8 of us here.

Around 1530, the wind increased to 30 miles per hour from the northeast, blowing embers over the line. Then the wind subsided for a brief time. When the wind began again, it was associated with the frontal passage and blew strongly out of the northwest. The spot fires below the main fire were in direct alignment with topography, slope, and wind.

The spot fire rapidly ran up the drainage. With no escape routes or safety zones, the fire trapped Clayton and his men at the dam in the drainage. Whether Clayton and his men actually started down to the spot or not was never determined.

As you walk up the ridge from Stand 2, you will come to this point with a vantage of both Clayton Gulch and Post Point. If time is limited, you can use this as an alternate location to conduct discussions for both Stand 3 and Stand 4. This location is identified as Stand 2A on the maps and in the Facilitator's Field Reference.

The distinctive vegetation pattern below Clayton Gulch shows the old burn scar and the location of the spot that would initiate the firestorm.

The Clayton Gulch memorial is on the ridge to the north and just above the gulch where the actual fatality site is located. This is the second memorial built in 1938 by the CCCs.

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.

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.

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.
