Hyde Park Mastodon Research: Plant Macrofossils

Not only can tree rings tell scientists how old a tree was when it died or was cut down, but it also reveals a lot about the weather when that tree was alive. Scientists have looked at large pieces of wood recovered from the bottom of Lozier Pond to help piece together a tree ring chronology. It is hoped that this wood, along with other Pleistocene and Holocene sites in New York and western New England, will allow a tree ring chronology for the northeastern US to be constructed. At left, Carol Griggs works with logs from a site near Ithaca, New York, where the wood found in glacial sediments may be 14,000 years old.
