The aerial picture was taken 25+ years ago with a Yashica twin lens reflex in medium format. The film was Kodak Ektachrome, known for its rich renditions of greens and blues. The film process was E6 done personally by me in the photo lab at the University of Maine. –rdorman
I took the photo as my spouse, R., was flying. We don’t recall exactly but believe it’s Hasting island on the Androscoggin River where ages ago the glacier bent and diverted the river, leaving an anomaly — watersheds divided, with tributaries flowing northward and one southward; the lake-spawned Crooked River flowing out of Songo Pond.
And here’s a description from page 214 of David L. Kendalll’s Glaciers & Granite: A Guide to Maine’s Landscape & Geology. He was a mining geologist, doing mapping and field research, his book recommended to me by a geology professor at UMF in the 1980s. It’s now falling apart. –sdorman
From Newry to Bethel the valley becomes narrower. The Androscoggin valley upstream from Bethel is scarcely wider than the river, and the highway steadily climbs westward. There are good views, especially to the north, of rugged, steep mountains with many bare cliffs but rounded tops. The highway leaves Maine in scenic mountain country.
In New England these flat lands are called intervales and are the only farmable land in the mountains. There are numerous readouts through mica schist along the highway, and beyond North Newry pegmatite veins are common, the coarse-grained minerals visible even from the car.
