This is a photograph of the region imaged by the MODIS Rapid Response System on March 22, 2004 at 11:30 EST.
It was cropped from a very large, 9MB, image. Smaller versions as well as the original may be seen Here.
The MODIS satellites are in a roughly polar orbit and obtaining decent images of Temagami can be hit or miss. Sometimes the geometry of the satellite's path and the sun's location isn't optimal or the pass occurs when the area is obscured by darkness or cloud cover.
Note in this image how the area burned in 1977 is obvious even though the snow pack is still on the ground. |

Dave:
A couple of questions. Did you supply the summer NOAA image that Brian has posted in the Newsbriefs?
Do we need special software to cut out a piece from a full sized NOAA main image or can we do it using a home computer by pasting it into a photoimage program?
The summer image Brian has put on the website shows only too well what has been going on both in Temagami and around Temagami. The image shows pretty clearly that the trees around Temagami have all been clearcut, leaving only Temagami for the loggers to move into. It doesn't provide much comfort to look at these images and reflect on how well our forest industry has been practicing sustainable forestry.
It looks as if we have all been getting a snow job from both the industry and the MNR.
Clearly the area in the Muskegon Wildlands is taking a huge hit now, as we focus our attention in other areas such as, South of Bob Lake.
Dave, any advice you could provide to help us to access more of these types of pictures would be very useful.
Thank you for sharing the above image with us. |

Satillite images also show all the golf courses and gravel pits that scar the landscape where I live.
It is really disturbing to see this image of Temagami. |

Ed, Dave did not supply the sat images I used, but these images on the link are from the same satellite. Nice discovery, Dave.
You can really see the difference between the light-grey hardwood forests (aftermath of fire or logging), which are missing their leaves, and the darker-grey softwood forests that still exist.

But what I think is most interesting is Domtar's giant clear-cut just north of Lady Evelyn Lake and moving each year in a SW direction toward Maple Mountain. It's the grey area marked with the arrow.

Hi Tess
What is it about the photo you find so disturbing, I think the photo is very interesting. The fire in 1977 was a natural occurance, the forest there appears to be regenerating just fine. I fly over this area every week the only large clear cut I can think of is the one mentioned by Brian. There are some large clear cuts NW of Lake Wahnapitae but they are not visible in this photo. To see what a big clear cut looks like post some images from the Hearst and Kap areas. |

Bush_Pilot:
I thought that most of the Hearst and Kap areas were cleared out a long time ago. How well are those areas recovering? At the same rate as the burned over area South of Obabika Inlet?
Or do you get over that way often?
Can you see much logging activity North of Red Squirrel and East of Aston as you pass over the area?
Look forward to your comments.
Thanks

Ed,
The MODIS satellite yields images with resolutions as high as 250M. That is to say, each pixel is equivalent to 250M across the ground. Any photo editing software will allow you to crop and save a portion of the image. I used Adobe Photoshop 6.0. The cropped image as posted is actual size, that is 250M/pixel. Some folks may run into problems trying to manipulate 9MB size images on their older PC's.
The high resolution original is quite impressive showing a frozen James Bay south to Washington, D.C. I can't wait to see some color start to appear in the satellite photos. |

Thanks for the info.
I did try to download the 9MB image and I had problems. I got a good bit of it and could see the Missinaibi river including Portage Island at the junction of the Mattagami and lots of other detail, but then I started to lose large sections of it as the download continued.
Maybe my daughter will see this and try it on her lap top, cut out the temagami section at 250m and send it to me.
It's a pretty fascinating picture to look at especially if you know the areas and it will be interesting to look at new pictures as the summer approaches.
Thanks again, Dave
