Dust and smoke issues in the Great Basin Unified Air Pollution Control District

Lion Fire smoke over the top

Posted by admin on July 28, 2011

The Lion Fire ( grew to 16,350 acres yesterday, July 27, 2011, as the Sequoia National Forest continued to ignite new areas, burning back from terrain features such as rocky ridges and creekbeds in order to establish containment lines.  They have been employing this strategy for the last several days causing a dramatic increase in acreages burned per day and smoke emissions (see burn progression at Lion_7-27-2011.  We’ve all seen and experienced the smoke.  Although only listed as 15% contained, the fire is pretty successfully boxed in by these “burnout” operations.  Therefore, growth and smoke emissions should drop off dramatically in the next few days.

Below are two photos from yesterday at about 6:00 PM looking north from Haiwee Reservoir and from just south of Olancha.  Luckily, for many Inyo County communities, much of the smoke went up and east, over into Nevada.

A large portion of the smoke plume dispersed north however, as seen from this satellite image at 2:10PM, and settled into the upper Highway 395 corridor later in the afternoon and evening.
