Rain gives Canyon Fire crews window to protect Native allotments

Light precipitation slowed the Canyon Fire #174 west of Rampart on Thursday, giving Chena Hotshots and smokejumpers a window to keep cutting control line around two Native allotments and a cabin on the north bank of the Yukon River.

The fire, ignited by lightning on June 11 and now estimated at 409 acres, is burning in a Limited Management Option Area — meaning agencies would normally let it play its natural ecological role. They're not, because Native allotments receive full federal protection status.

What's substantive about the response this week: crews are working two separate sites, in two different directions from the fire. The Chena Hotshots have established a camp at one allotment roughly 1.5 miles south of the fire and are cutting line around it. Smokejumpers are working a second allotment and a cabin about 3 miles to the northeast.

Three miles is a meaningful distance.

Fire managers don't typically pre-position crews that far from a fire's edge unless they expect substantial movement. Alaska's boreal forest of black and white spruce — the same fuel type the Canyon Fire is burning through — can move quickly under dry conditions, and the fire's current "smoldering" behavior is typical of how Interior boreal fires persist between active runs: slow consumption of duff and peat below the surface, then flare-ups when wind, temperature, or moisture conditions change. The pre-positioning at both the south and northeast sites suggests managers are hedging against the fire moving in multiple directions across the coming weeks.

"Because it is burning in a Limited Management Option Area, it is generally allowed to play its natural ecological role unless it threatens identified sites of value," the U.S. Wildland Fire Service said in its June 18 update. "However, Native allotments receive full protection status."

Rampart, the nearest community, sits on the south bank of the Yukon roughly 20 miles east and is not currently threatened. Smoke is visible to boaters and aviators traveling the Yukon River corridor.
