Paul:

Sorry that Minnesota has made so much smoke. See this pair of pictures.
The first is from Sept 13, when the fire blew up and ran 16 miles on a strong westerly wind.

Note the pyrocumulus cloud--basically a thunderhead formed by condensation of the water vapor liberated by the burning of organic material, which is the bright white puffy looking area just to the southeast of the start of the smoke plume, but still embedded within the plume.

Next is a satellite image taken three days later over Poland, Ukraine and Russia--the smoke from the Minnesota fire has made its way to eastern Europe, as shown by the plume within the yellow circle.

Turning 94,000 acres of forest into smoke yields a huge amount of smoke--enough to circle the globe.

Today the fire is 54% contained, due to an inch of rain last week, and some rain is forecast for tomorrow, so hopefully the fire has reached its maximum size.
We have already put in a proposal for rapid response money to do before and after comparisons of vegetation and mapping of the severity of the fire, which is the biggest in standing forest in MN since 1894 (other bigger fires burned in the slash created by land clearing of European settlers in the early 1900s).

Lee,

Well, at least the smoke provided enhanced beauty in our sunsets, even if my eyes were itchier and my sinuses a little irritated.

The following page shows MODIS satellite images of the burn scar:

Also, Colorado State's RAMMB (Regional and Mesoscale Meterological Branch) tracked the smoke cloud all the way to China - last seen on MTSAT-2 Asian weather satellite images around 9/20-21?, but the online image is real-time only and no longer available.

Maintain the BWCA's 'wilderness' character

'Untrammeled' does not necessarily mean 'untouched,' but it does mean a place where humans now exercise restraint.
"There is no better way to save biodiversity than by preserving habitat, and no better habitat, species for species, than wilderness." --Edward O. Wilson

Nearly two months after being ignited by lightning, the Pagami Creek Fire in northern Minnesota was nearly contained when Landsat-5 acquired this image on October 10, 2011. Since August 18, the fire has been burning in the Boundary Waters Canoe Area Wilderness in Superior National Forest. As of October 11, the fire had burned 92,682 acres and was 82 percent contained. Apart from a faint hint of smoke, there is little sign of current fire activity in the image. The burned forest, however, is charcoal-colored, in contrast to the green forest around it.

ENTS:

As of today (Oct 22) the Pagami Creek fire is 91% contained, and because an inch of rain fell last week combined with rapidly cooling weather, they are removing crews and equipment from the area. A research program funded by the National Science Foundation rapid response fund is underway, headed by Phil Townsend (U of WI), Peter Wolter (IA State), and Brian Sturtevant, Randy Kolka and others at the US Forest Service. I am included as a cooperator. This project will obtain immediate data on the impacts of the fire on vegetation and soils, setting the stage for a larger ongoing research project later.
