Hooper Garnet Mine
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.)

Blown away by Bancroft: Part IV
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.

Blown away by Bancroft: Part III
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.

Blown away by Bancroft: Part II
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!

Blown away by Bancroft: Part I
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!)
Jessica Ball is a volcanologist at the U.S. Geological Survey, researching volcanic hydrothermal systems and stability, and doing science communication for the California Volcano Observatory. She previously worked at the Geological Society of America's Washington DC Policy Office, learning about the intersection of Earth science and legislative affairs. Her Mendenhall postdoc and PhD focused on how water affects the stability of volcanoes, and involved both field investigations and numerical modeling applications. Her blogging covers a range of topics, from her experiences in academic geosciences to science outreach and communication to her field and lab work in volcanology.
