Summary: The Washburn Fire was reported on July 7th, near the Washburn Trail in the Mariposa Grove area of Yosemite National Park. A full initial attack response was dispatched including Yosemite NP Fire resources as well as state and local cooperators. California Interagency Incident Management Team 13 assumed command of the fire Saturday, July 9th and will manage the incident as a full suppression fire.

The fire was active last night and with the current warming trend, increased fire activity is expected for today as well. While structure wrap is not currently being used on the giant sequoias, firefighters are proactively protecting the Mariposa Grove through the use of a ground-based sprinkler system. This increases the humidity in the area around the trees and combined with the removal of ground fuels, the ground fire risk is greatly reduced. Yosemite’s fire management program has for many years utilized a wide variety of methods to reduce the fuels and minimize the risk of fire to the over 500 mature giant sequoias as well as the entire National Park.

Terrain and Fuels: The fire is burning in difficult terrain which presents accessibility issues for firefighters. Heavy fuel loading from a period of high tree mortality has resulted in a large number of standing dead and fallen trees which create hazardous conditions for firefighters. The current fire location does not provide a large number of natural barriers which are often used to slow or stop the spread of a fire. Consequently, a great deal of hand and dozer line is being constructed.

Aircraft Incident: On Saturday, July 9th a tree branch was sent into the air from the powerful updraft produced by the fire. As it dropped back to earth, it narrowly missed two firefighting aircraft. Fortunately, there were no injuries and no damage. We are all grateful for the hard work and risks taken by everyone involved with the firefighting effort.

Evacuations & Closures: Wawona, Wawona Road (Hwy 41) south of Yosemite West, and the Mariposa Grove are closed until further notice. All other areas of Yosemite National Park are open.
