The cliff face consists of granitic gneisses cut by basaltic dikes. It is elevated above the surrounding area by a fault near the edge of the Adirondack Mountains. |

I had originally hoped to get into the Barton Garnet Mine to shoot a macroGigaPan of the famous Gore Mountain garnets, but unfortunately I was a little too early in the season. The garnets at the locality featured here are from a now-abandoned garnet mine in the area that is currently located on state lands. The garnets here aren't as huge as at Gore Mountain, but they're nothing to scoff at. I shot this GigaPan with autofocus on. I was going to take this into Photoshop to clean up the out-of-focus areas at the margin between the outcrop and the distant trees, but I in the end I decided it just wasn't worth the effort at this time, because that's really not the most interesting part of the image, anyhow. The unusual arc of the stitched image is likely the result of inaccurate leveling of the Epic100 robot. That's due to the fact that I had to take the robot off the tripod and place in on a rough rock surface and hold it in place by hand in order to get the correct angle perpendicular to the face of this outcrop. |

Just down the road from "The Trainwreck", this is another roadcut through marble in the Adirondack Lowlands east of Gourvernour, NY. The "Steer's Head" is located left of center and there are more boudinage features in the marble further to the right.
Can you spot Edi and Berti? |

Large panorama of a roadcut near Gouverneur, NY known as "The Trainwreck". There are remarkable boudinage features in this high-grade marble that mark the train cars scattered off the track. |

This GigaPan illustrates an exposure of the basal Cambrian Potsdam Sandstone nonconformably overlying Precambrian gneisses at the eastern edge of the Adirondack Mts uplift. My field assistants took time out from exploring this remarkable contact to pose for the GigaPan. Berti is standing directly on the unconformity surface and Edi is down among the vertically foliated basement gneisses. One of these days I'll teach one of them to run the GigaPan rig so that I can pose in the pictures myself. ;-) |

Just for fun I took some photos of canoers on Osgood Pond and it turned out only slightly wierder than I expected.

Anorthosites metamorphosed to granulite facies underly most of the High Peaks region of the Adirondack Mountains in upstate New York. This sample illustrates beautiful examples of garnet coronas around pyroxenes. This one's for you, Chief! |
