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?
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.
A classic outcrop found at the Soudan Underground Mine State Park consists of folded layers of white chert, red jasper and metallic hematite.
Your assignment is to decipher the geologic history of the rocks seen in this roadcut. Good Luck!
