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

Pilot & Crestview Prescribed Burning

Posted by admin on October 20, 2011

The Inyo National Forest did a broadcast burn, Pilot/Corsair, of approximately 156 acres yesterday a few miles southeast of Mono Lake.  Today they will burn another 100 acres of their Crestview broadcast burn.  The photo below of Pilot/Corsairwas taken at about noon from the Crooked Meadows turnoff from East State Route 120, facing southeast. The smoke plume got vertical lift of about 5,000-7,000 feet above ground-level, allowing for good dispersion to the ESE (see 1:45 PM satellite image below).

 

There was some concern, based on fire weather predictions, that the winds would change to out of the north later in the afternoon and evening.  This did not materialize though as the smoke plume continued to go east towards nightfall, as can be seen looking up Owens Valley from East Line Street in the photo below.  The smoke stacked up against the White Mountains some, but then dispersed on over into Nevada.  Remote Automated Weather Stations (RAWS) near the burn location actually recorded the winds shifting to the south overnight.
