Rock City, NY
August 24, 2011
Strange as it may seem the photo above taken at Rock City Park near Olean, New York, is of a natural rock formation. Recently I went with a group of fellow photographers from the Rochester area to visit this unusual geologic park. One of our members had been there years before and suggested it would be a good outing. These rocks were initially formed by the erosion of the Acadian Mountains about 380 million years ago in the middle Devonian. The glaciers of the Pleistocene ice ages, about 1.8 million years ago, carved such local features as the Finger Lakes but the area around Rock City remained unusually clear of ice. The glaciers eroded much of the looser shale and other sedimentary rocks leaving the older quartz conglomerate called puddingstone. In the park, there are huge rocks the size of buildings all over the place with large crevasses that have opened up due to the ground shifting over time and erosion, and there are trees and flowers growing in the crevasses. Here's a link to the photo album created by my meetup.com group that has photos from several of us who attended that day. Photo taken June 26, 2011.
Photo details: I used HDRI (high dynamic range imaging) and shot this with my Canon 5D and 24-105 mm lens at various exposures and combined the images into this picture.
