CHEYENNE, Wyo. (Wyoming News Now) - The Burned Area Emergency Response (BAER) team assembled by the Medicine Bow-Routt National Forests and Thunder Basin National Grassland (MBRTB) recently completed their data gathering and verification field work of the Mullen Fire burned area. The team has finalized its Soil Burn Severity, Debris Flow Probability, and Interactive Debris Flow Probability maps.

“That assessment looks at the potential risks that are out there on the landscape and tries to determine if there are ways to mitigate that risk for human-life, infrastructure and property and natural and cultural resources,” BAER Team, Dave Gloss said.

BAER post-fire assessment teams use the soil burn severity data to identify areas of concern on National Forest System lands where increased soil erosion, accelerated surface water run-off, and debris flows have the potential to impact human life and safety, property, and critical natural and cultural resources from rain events.

The Mullen Fire team says it partnered with the U.S. Geological Survey to produce a debris flow probability map that uses data related to basin morphometry, burn severity, soil properties, and rainfall characteristics to estimate probability and volume of debris flows that may occur.

The BAER Team says it found that the Mullen Fire burned in a mosaic pattern across the landscape. The fire is currently 176,878 acres and 97% contained.

“The Mullen fire was very large 275 square miles, so after a fire burns there still potential for hazardous like conditions may still exist on the landscape.”

In the aftermath, The Mullen Fire will have lasting impacts on the Medicine Bow-Routt National Forests, as well as surrounding public and private lands.
