Gary Thornbloom will show his slides of Greenland, a spectacular but rapidly changing part of our world. While on the world’s largest island, Gary witnessed the booming of glaciers and the sharp crack of icebergs breaking up; Arctic foxes were his companions at camp. He visited the communities of Ilulissat and Uummannaq, and hiked to pre-Christian burial sites, rock fox traps, and tent rings. Going north has always appealed to Thornbloom — since the eighties, he has plied the wilderness waterways of Maine, northern Minnesota, Alaska, the Hudson Bay, and Iceland. He has also worked to protect many of special places in Pennsylvania, and for the past 15 years has been a leader in the Moshannon Group of the Sierra Club.
