The posted coordinates will take the rim of a long dead volcano.
Feel free to dive right in!
About 1.3 Billion years ago a primeval continent slammed into the
Canadian Shield. The slow impact collision caused various faults in
the area, and caused the earths crust to fold upwards, lifting the
earths mantle into a bulge. This impact was known as the Grenville
Orogeny and produced such pretty things as the east coast, and the
Appalachian mountains.
Anatomy of a volcanic pipe
Unlike most volcanoes, the Callander pipe is the result of a
chemical reaction deep within the earth. "deep-origin" volcanoes
result when magnesium rich magma interacts with water and carbon
dioxide causing volatility of the molten rock. Deep-origin
volcanoes such as this are born up to three times deeper then most
other volcanoes. The magma is pushed through the layers of the
crust towards the surface. As it rises the water and carbon dioxide
turn into a high pressure gas and expand quicker, as well as
corrode the above rock strata as it approaches the surface.
A violent supersonic eruption occurs when the pipe reaches the
surface in much the same principle as a cork in a champagne bottle
(but much larger, noisier and nastier). Because of the volatile
nature of the magma, water and carbon dioxide.
Over the last billion years or so, things have cooled off, and the
area has become more pleasant. The rocks have been crushed, torn,
uplifted, eroded, heated, cooled, burnt, and gauged with glaciers
over the years (and not necessarily in that order) turning this
once amazing mountain range; as high as the himalayas, into the
landscape before you.
Lake nippising itself has 3 volcanic pipes including this one, and
the Manitou pipe (responsible for the Manitou islands). The area
also has 5 named Batholiths (Exposed lava fields exceeding 100
square kilometers) such as the nearby Bonfield and Powasson
Batholiths, and various Fault lines.
To Log this cache:
- Venture as close as you are willing to get to the volcanoes
center (yes, this can just be the beach in Callander..) and take
the water temperature with a thermometer, and a picture of your
team (post with log)
- Drive somewhere else on Nippising lake and take the temperature
with a thermometer. Feel free to include these answers in your
log
- If there is more then 10 degrees difference in the water
temperature.. evacuate!
- Email me the answer to the following: From the above
description and a little internet research, does this seem like a
"Lamproite pipe" or a "Kimberlite pipe"?
Winter Requirements:
As for many months of the year the lake is "unavailiable" to take
water samples from, please attempt the following (after ensuring it
is safe)
- Photograph your self and your crew standing on the centre of
the volcano (approximately the centre of the bay)
- Email me the answer to the following: From the above
description and a little internet research, does this seem like a
"Lamproite pipe" or a "Kimberlite pipe"?

Great colours here at North Bay area this week even though cloud cover and light rain prevent the full splendor. Always like the geology or is it geography or whatever lessons we get at these Earth Caches. Ummm that water was not very hot so we guess we are safe. Took noted temperatures and did our research. Will send e-mail and attach image to log when we get home (no connection to camera at this PC station. TFTC

The kids have swum nearby on several occasions and I must confess, we were all completely oblivious to the geology involved here. Thankfully, the kids were never in any real danger, phew.
Since only a 1/4 of the team was present, only me and my shadow, smiled for the photo.
Answer sent via email. TFTEC

Ventured back from North Bay with Mrs FC; stopped to do this great cache... although we couldn't find a suitable vendor of inexpensive thermometers, so I have a shiny wall thermometer now... TFTC!!
