Recently, I finally trekked across NY state to the Adirondacks and visited the Gore Mountain area, home of several garnet mines. Now, these aren’t like the garnets I was showing in my Bancroft photos. These are HUGE. Garnets as big as your fist. The two best places to find them are at the Gore Mountain Garnet Mine (which charges an entrance fee and by the pound for what you take out), and the Hooper Mine, which is no longer in operation BUT is also free. Being grad students, my friends and I went for the free option. (The garnets at Gore mountain are, admittedly, bigger, but there is a limit to how much rock even I am willing to drive back across the state.)

On the last morning of our Bancroft field trip this past April, we continued our journey through the metamorphic faces diagram with a stop at an outcrop north of Bancroft on ON-28, in the amphibolite facies.

On the second afternoon of our trip, we finally began moving out of the greenschist facies into the amphibolite facies – higher pressures, higher temperatures and a different set of minerals.

On the second day of our Bancroft trip, we started out in the greenschist facies and moved on into the amphibolite facies of the metamorphic pressure-temperature diagram. And, of course, took lots of photos!

Back in April, I finally had a chance to accompany the petrology classes from UB and SUNY Fredonia on UB’s annual trip to Bancroft, Ontario. I’ve been trying to go on this trip for years, and I’m glad I got to before I graduated, because, WOW. Bancroft is chock full of some pretty amazing things (especially if you’re into petrology, mineralogy, structure, glaciology, and pretty much everything else – it’s known as the ‘Mineral Capital of Canada’, for one!)
