Fire Update - October 16, 2017

October 16, 2017 Posted by: Yosemite Fire Information

Prescribed Fire Update

On Saturday Yosemite fire managers made the decision to postpone the prescribed burns in the Mariposa Grove and the Soupbowl until further notice. A dry stable air mass with low relative humidity was the primary driver for being out of prescription.

Prescribed fire is a very important tool for reducing excessive fuel build up near our communities in order to reduce severity of future fires. When the conditions are right, we hope to proceed with these prescribed fires.

WTREX (Women in Fire Training Exchange)

This group will continue working with Yosemite Fire crews.  You might see a high percentage of women firefighters from various federal, state and other non-profit agencies assisting the park with fire management activities. Currently only 10% of wildland fire positions are filled by women. This international 12 day training is comprised of 90% women.  For more info (

Fire managers are working with the local Air Quality Pollution Districts and will be monitoring smoke impacts to the park and local communities. Due to moderate smoke production from the Empire wildfire, Yosemite Valley will experience smoke, this will be compounded with campfire smoke until the morning inversion lifts.
