This incident is no longer being updated.

The Tincup Fire was discovered on July 30 approximately 30 miles northeast of Soda Springs near the Grays Lake Wildlife Refuge Headquarters. The lightning-caused fire is creeping in dead and down fuel with minimal fire activity observed. The fire is spreading towards the northeast.

The Caribou-Targhee National Forest is aware of several unique values in the area including private in-holdings, recreation trails, Hwy 34 and range infrastructure. Due to the location of the fire and the observed fire behavior, fire officials feel it important to let the Tincup Fire play its natural role in the ecosystem. The mixed conifer and aspen ecosystem found in southeast Idaho has evolved with and depends on fire. This does not mean the fire will burn without human intervention. Active measures will occur to create fuel breaks on forest service lands between public and private lands to prevent fire spread onto private lands. Should fire activity increase or threaten private resources, additional firefighting tactics will be implemented.

Allowing the Tincup fire to burn naturally will assist the forest in achieving a variety of resource benefits including:

Reducing heavy dead and down fuel loading that is above the historic range due to past suppression activities, which will reduce the risk of future high-intensity wildlife by removing excessive fuel loading.

Stimulating aspen regeneration through fire’s natural disturbance, which will increase habitat for a variety of big game species.

Reducing the risk of firefighter exposure

Increasing plant diversity
