John K. DeLaski, M.D. practiced medicine in the Penobscot Bay region of Maine and, in addition, was a naturalist with keen powers of observation. His study of the landscape led to the conclusion that a thick glacier had overtopped the highest hills, flooded all of Penobscot Bay, extended far to the east and west and probably was part of a greater continental glacier. He published these very critical field observations and inferences in numerous articles in local newspapers and magazines, and in the American Journal of Science in 1864. His work put him on the “team” of Benjamin Silliman, James D. Dana and Louis Agassiz as an advocate for glaciation as the regional land shaping force opposed to that of the Biblical Deluge, a major scientific conflict of the day both in North America and Europe. He remained a shadowy player, in the background, but clearly contributed critical observations to the argument through personal interactions with Agassiz and other prominent naturalists. They incorporated DeLaski’s observations into their own presentations, often without giving him credit. John DeLaski’s summary work, a 400 page handwritten manuscript for the book, “The Ancient Great Glacier of North America”, was dated 1869. He died in 1874 and the book was not published. The historic significance of DeLaski’s unpublished book is based upon its startling contribution to one of the major scientific questions of the day of whether the surficial geology of northern U.S. and Canada was caused by the actions of the Biblical Flood or by continental glaciation. If published, this would have been the first book on this continent, at least, to present a holistic discussion of the controversy in which he presented his critical observations of the surficial geology in Maine, southern New England and New Brunswick, Canada and concluded that these depositional and erosional features must be of glacial origin. DeLaski then incorporated other evidence into the book for glaciation reported by others from the region during a decade or two, and from the mid and far west and Canada to advocate that the entire region was covered by an ice sheet that was at least 5,000 feet and probably much thicker over interior northern U.S. and Canada and which terminated along a glacial margin which extended from southern new England as far westward along the courses of the Ohio, and Missouri Rivers. All this was done while most “naturalists” still advocated the Biblical Flood to explain the major components of the surficial geology in North America and abroad. DeLaski’s book containing his critical observations of clearly so many landscape features of glacial origin, if published would have been a pivotal document that would have strongly supported those arguing for glaciations in the glaciations vs. flood international argument.

How the idea of deep time transformed how Americans see their country and themselves During the nineteenth century, Americans were shocked to learn that the land beneath their feet had once been stalked by terrifying beasts. T. rex and Brontosaurus ruled the continent. North America was home to saber-toothed cats and woolly mammoths, great herds of camels and hippos, and sultry tropical forests now fossilized into massive coal seams. How the New World Became Old tells the extraordinary story of how Americans discovered that the New World was not just old—it was a place rooted in deep time. In this panoramic book, Caroline Winterer traces the history of an idea that today lies at the heart of the nation’s identity as a place of primordial natural beauty. Europeans called America the New World, and literal readings of the Bible suggested that Earth was only six thousand years old. Winterer takes readers from glacier-capped peaks in Yosemite to Alabama slave plantations and canal works in upstate New York, describing how naturalists, explorers, engineers, and ordinary Americans unearthed a past they never suspected, a history more ancient than anyone ever could have imagined. Drawing on archival evidence ranging from unpublished field notes and letters to early stratigraphic diagrams, How the New World Became Old reveals how the deep time revolution ushered in profound changes in science, literature, art, and religion, and how Americans came to realize that the New World might in fact be the oldest world of all.

If parks could speak, what would they say? Historic Acadia National Park is a vibrant collection of true stories that share different aspects of Acadia National Park’s history. From its glacial origins, to its rising peaks near the tourist-town Bar Harbor, Acadia has a unique and fascinating history for Down Easters and tourists alike. Many of the tales focus on some of Maine's most famous land formations including Pulpit Rock, Sargent Mountain Pond, Mount Desert Rock, Otter Creek, and even the Trenton Bridge. Learn about the people who first walked these woods and how Acadia National Park evolved into the national treasure it is today.
