Teton Interagency Fire

Grand Teton National Park is planning a prescribed fire for 196 acres near Mormon Row, on part of the Hayfields Restoration Management Area near Mormon Row starting April 9, 2026.

Key Details

• Start Date: April 9, 2026
• Location: East of Blacktail Butte and west of Mormon Row, between the Gros Ventre and Antelope Flats roads
• Project Scope: The 196 acre prescribed fire area is part of the larger 4,000 acre Hayfields Restoration Management Area.
• Primary Objective: The burn aims to restore fallow hayfields in Grand Teton National Park to native vegetation. Removing non-native vegetation will also benefit wildlife, such as bison, elk, pronghorn, sage grouse, and songbirds, and will reduce fuels near historic park structures in case of a wildfire.

Public Impact & Safety

• Smoke Visibility: Smoke will be visible on the day of the burn, mostly during the warmest part of the day. With cooler temperatures in the evening, smoke may linger and accumulate in low-lying areas. Visit https://fire.airnow.gov/ to monitor smoke.
• Road Safety: Drivers are asked to slow down and use caution as fire vehicles and personnel may be working near the roadway. 
• Area Access: No area closures are expected but park staff may pause traffic briefly to allow firefighters to safely work along the road, if necessary.

Monitoring: Safety factors, weather conditions, air quality, personnel availability, and environmental regulations are continually monitored as part of any fire management operation.
