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.

 The Jackson Ranger District plans to resume prescribed fire operations at Munger Mountain as early as April 8, 2026. These operations are part of a multi-year effort to reduce overgrown vegetation and protect local communities from future wildfires.

Key Details

• Start Date: As early as April 8, 2026, depending on weather and fuel conditions.
• Location: The Munger Mountain unit is located approximately five miles south of Jackson, WY.
• Location: The Munger Mountain unit is located approximately five miles south of Jackson, Wyoming, near Highway 89/191 and Evans Road.
• Project Scope: Fire crews aim to treat portions of the 1,663-acre unit using a "mosaic pattern" to create a diverse landscape.
• Primary Objective: To decrease hazardous fuel loads and improve wildlife habitat for species like elk, moose, and mule deer. 

Public Impact & Safety

• Smoke Visibility: Smoke will likely be visible from the surrounding area, including Highway 89/191 and parts of Jackson Hole.
• Road Safety: Drivers are advised to slow down and use headlights if smoke is present

Taylor Mountain is one of many treatment units in the Teton to Snake Fuels Management project. The project covers a large area along western Teton County and is in and adjacent to the Palisades Wilderness Study Area.

This area is considered one of the highest fire risk areas on the Bridger Teton National Forest. The existing forest fuel conditions and prevailing winds can create and push severe wildfire toward high density residential areas.

Taylor Mountain Unit is located adjacent to the Hidden Hills Subdivision and Butler Creek. Fuels within the unit vary from shrub stepp, Aspen stands, and mixed conifer stands.

Community is one of the strongest tools in fire safety. When neighbors know each other and work together, preparedness becomes a shared responsibility rather than an individual burden. Thank you Hidden Hills and Butler Creek Subdivsions for your collaboration and support with the Taylor fuels treatment projects over the years.
