InciWeb Post for Indian Fire

Posted by admin on August 13, 2012

Thanks to the Inyo National Forest/BLM Bishop Field Office for supplying InciWeb with Indian Fire update information.  Below is an image from a Great Basin UAPCD webcam at Mono Lake at 2:08 PM PDT on Friday, August 10, 2012.  There were a few other recent lightning-strike fire ignitions, but this fire was probably the largest contributor to the haze seen in the Owens Valley over the past few days.  Hopefully, the over 40 mph SW wind gusts associated with this afternoon’s thundershower won’t cause another large run on the otherwise 70% contained fire.

Bear Fire and Indian Fire

Posted by admin on August 9, 2012

The Bear and Poison Fires in the Sierra National Forest have merged (37.34, -118.96), retaining the name Bear Fire, and have combined for about 700 acres.  There is now an incident report on the InciWeb site (Thank-you to the Sierra National Forest for getting that posted).

A new incident originated yesterday from lightning southeast of Mono Lake (37.91, -118.86).  Within a day, the Indian Fire burned through about 5,ooo acreas of grass and brush, buffeted by the high winds of the associated storm cell.  Growth is expected to slow dramatically today under lighter wind conditions.

Poison & Bear Fires in Sierra National Forest

Posted by admin on August 7, 2012

The incident commanders reported that the Bear and Poison Fires near Bear Creek are still separated by a ridge.  They combine for about 170 acres, up from 35 acres yesterday, in dense fuels.  This fire would account more for the heavy concentration of smoke in the Round Valley and Crowley Basin areas than the Clear Fire reported in the previous blog post.  As yet, there is not a source of online updates for the fire, but that will be forthcoming.

Clear Fire’s smoke path

Posted by admin on August 7, 2012

Yesterday, primarily in  the afternoon, the Clear Fire burned another 500 acres or more to reach a total size of 1800 acres.

Below was the predicted travel path for smoke originating from the fire at 3PM and 4PM yesterday.  This appears to have been pretty accurate, as the smoke seemed to arrive overnight and looked fairly dense over southeastern Mono County this morning (as observed from Bishop).  The Bishop Paiute Tribe’s PM2.5 monitor recorded 23 ug/m3, about three times the annual average, but still below the 24-hour limit of 35.
