Bedrock Geology of Newton and Environs
October 26, 2019 @ 9:00 am - 12:00 pmFree
The bedrock geology of the Newton area tells a fascinating story of a time about 585 million years ago when Newton was part of the great southern continent of Gondwana and not far from the south pole. The rocks record a history of great volcanic eruptions and sedimentary basin deposits (the famous puddingstone!) in areas between the volcanoes. Join us and learn a bit about how the rocks tell us their story. This trip will not be one of the usual Newton Conservator “walks” since we will need to carpool to diferent sites in and around Newton to see the different rock types. If there is time and interest, we may choose to go a bit beyond Newton to view rocks within a volcanic caldera from that time. Meet in the parking lot at the entrance to the Hammond Pond MDC Reservation area-east, at the west end of Hammond Pond of of Hammond Pond Parkway near Rt. 9, behind “The Street” complex — near the movie theater (see Newton Conservators’ Walking Trail Guide, pg. 35).We will first visit rocks in the woods near here, then carpool to the other exposures. Trip will about 3 hours. If there is moderate rain or worse, the trip will be cancelled. You can call the leader the evening before if in doubt. Most stops are close to a road, but at one stop we will walk a few hundred yards into the woods, and there is a bit of scrambling to reach the exposure. Trip Leader: Chris Hepburn (617-964-1137)
