Pratt Rock Park Geologic History with Robert and
August 31, 2019
Zadock Pratt Museum presents Pratt Rock Park Geologic History with Robert and Johanna Titus, Saturday, August 31 at 1 p.m.
During their presentation, Robert and Johanna Titus, retired geology and biology professors, will discuss the geologic significance of the Pratt Rock site. This scenic and historic site preserves a complex geological past of particular interest. The sandstones and shales exposed at Pratt Rock were formed as river channel and floodplain deposits on the Devonian Age Catskill Delta, about 385 million years ago. A mere 16,000 years ago glaciers advanced down the Schoharie Creek Valley and sculpted much of what is Pratt Rock today. Following the presentation, there will be a guided hike at Pratt Rock in Prattsville.
Robert and Johanna Titus are well known in the Catskills for their newspaper and magazine columns, writing about the region’s geological history. They are authors of “The Catskills: A Geologic Guide” and the upcoming “The Catskills in the Ice Age.” You can learn more about their work at thecatskillgeologist.com.
