Mann Gulch is a gulch in the Gates of the Mountains Wilderness of the upper Missouri River, 24 miles (39 km) north-northeast of Helena, Montana, in southeastern Lewis and Clark County.
Mann Gulch is between Meriwether Canyon immediately to the south and Rescue Gulch immediately to the north, and the creek it contains flows into the Missouri in the canyon known as the Gates of the Mountains.
Mann Gulch is approximately 2.4 miles (3.9 km) southeast of Beartooth Mountain.
The fire is the subject of Norman Maclean's book Young Men and Fire and a topic in the prologue to Adam Grant's book Think Again: The Power of Knowing What You Don't Know (2021).
