Fwd: Keweenawan Rift


ooohhhhh!!! NOW I SEE THE PROBLEM. YOU DON'T LIVE ON EARTH. 

"The USGS also maintains a satellite called Landsat 8 (http://landsat.usgs.gov/) that is continuously collecting imagery of the Earth from space. If a sinkhole out in the lake was draining the waters of Lake Superior, USGS Landsat scientists would have been able to detect it. "

In my studies, a sinkhole 3 miles wide in the center of a Lake would be considered unstable seismic Activity, and a silty red excretion that turns tarry and black might be called magma.

Ms. Douglas, 
The following is in response to your July emails regarding the Keweenawan Rift, also referred to as the Midcontinent Rift. 
The Lake Superior region is underlain by a geologic feature called the Midcontinent Rift, which is now geologically inactive. Rocks related to the Midcontinent Rift form a narrow arc from about the middle of Kansas, through the Lake Superior region, curving under the lower peninsula of Michigan, ending at near Detroit. Most of the rift is hidden by younger rocks and glacial deposits, except in the Lake Superior region where rift rocks form much of the spectacular shoreline. The rocks that hold up the high ground in Duluth are part of the Midcontinent Rift. At the time of active rifting, magma erupted from a series of vents all along the trace of the central rift axis (from Kansas to Detroit). All volcanic activity related to the rift ended about 1,100 million years ago.
The Lake Superior region and the Midcontinent Rift are now geologically stable, meaning there is little if any geologic activity; for example, no earthquakes and no volcanoes. Lake Superior as it appears now is a geologically young feature when compared to the geologically old Midcontinent Rift. The lake occupies a deep basin carved out by glacial ice tens of thousands of years ago. The current drainage patterns of Lake Superior and the other Great Lakes are gradually changing, but on a time scale of thousands of years rather than very quickly. The National Oceanic and Atmospheric Administration has determined that current lake levels, which fluctuate only by several feet, are now controlled mainly by climate factors such as rainfall and winter ice cover.
The USGS has been studying the Midcontinent Rift for many decades and is confident that there are no current volcanic events. The USGS also maintains a satellite called Landsat 8 (http://landsat.usgs.gov/) that is continuously collecting imagery of the Earth from space. If a sinkhole out in the lake was draining the waters of Lake Superior, USGS Landsat scientists would have been able to detect it.  

Thank you for your interest in USGS science.

ALSO - The water has gone down below the table. It is not only pouring into the hole, it is drawing from the spring that feeds the lake, and I think it is in a circular vacuum with MAGMA. --Monica

I can't believe the USGS are really this idiot. I am describing a sinkhole which now has lava pouring out of it. The magma is not always visible, but a similar mineral deposit, possibly magma, is flowing into culverts by the mall... Please send me a response I can see. Dictator Petraeus is not a good excuse to allow my emails to be hidden.

USGS Response:
Hello,
Thank you for contacting the USGS regarding Lake Superior. Lake levels at Lake Superior are monitored by the National Oceanic and Atmospheric Administration (NOAA), along with asssistance from the U.S. Army Corps of Engineers and their Canadian federal counterparts. More information can be found at their website. You can see average monthly water levels for the lake here. Lake levels don't look unusally low based on this data, but if you have any follow-up concerns you can email NOAA's Great Lake Research Laboratory at:glerl@noaa.com.
Regards,
USGS Menlo Park, CA
Please take a moment to tell us how we did!

Message: Dear USGS, I don't know if you are aware of the changes in the lake here in Duluth, that is Lake Superior. You probably will not be able to see any surveillance that has integrity. The ridges are showing and the water appears to be pouring into a hole. The rain filled the lake up, but only for a few hours. It appears the land is all caving down for at least 25 miles out. I have posted some items as far back as June 27th - www.helichrysumandbirch.blogspot.com
