Geological GigaPans from Minnesota.
Can you find the anorthosite xenolith in this roadcut of diabase? (Hint: it's LARGE.)
Can you find the bald eagle?
A classic outcrop found at the Soudan Underground Mine State Park consists of folded layers of white chert, red jasper and metallic hematite.
Another GigaPan shot in a hurry under partly cloudy conditions that nearly drove me mad. Turned out better than I expected, all things considered.
Edi and Berti climbed atop a boulder of banded iron formation (BIF) in Soudan, Minnesota.
... in the rain.
I got here rather late in the day, so the lighting was definitely not optimal.
A relatively quick overview shot, just before the mine museum closed.
Your assignment is to decipher the geologic history of the rocks seen in this roadcut. Good Luck!
