At the historic Ely Greenstone outcrop, Mike and Mary covered up the interpretive sign so
we'd have to figure it out for ourselves!
Bereket made a model of the pillow basalts using toothpaste.
Pam checks it out here.
Down the road a little way west of Ely is a better outcrop of the pillow basalt.
The best pillows are the lumps at the top of the outcrop.
Then it was on to the rhythmically banded turbidites, here being studied
by Nick and Ross.
This picture shows the banding.
After supper there was a killer card game.
On Tuesday we had a geological tour of the Hibbing Taconite Mine by
the mine geologist, Mike Orobona.
Out in the Hibbing Taconite pit, Megan checks out a piece of ore with Bereket.
It rained the whole time.
But our spirits weren't dampened!
Mike explained the different layers and zones in the ore body, and showed
us examples of each of the major ones.
