When: September 25, 2024 from 8:00 a.m. – 6:30 p.m.
Meeting Location: Hilton Lake Champlain
CEU’s: 10 hours
The field trip will feature all new sites visiting these fractured rock locations:
Stop 1: The Champlain Thrust at Lone Rock Point (Burlington) juxtaposed the Cambrian Dunham Dolostone of the hanging wall with the Ordovician Stony Point shale of the footwall. Private wells yields are higher in the dolostones than the shales, which can have water quality issues (fluoride, sulfide).
Stop 2: The Town of Franklin recently drilled a bedrock well with groundwater producing zones at depths of ~195’ (7 gpm) and 300’ (300 gpm). Using geologic mapping and geophysical logging, the first zone was determined to coincide with base of the Cheshire Quartzite hanging wall (Hinesburg Thrust) and the second was within the Dunham Dolostone footwall.
Stop 3: Because existing wells and springs are completed in the low-yielding Underhill Formation, the Town of East Berkshire needs more water. A nearby high-yielding (80 gpm) private well was drilled into the hanging wall (green phyllite) of a Silurian reverse fault and completed in the footwall (phyllitic quartzite) and is a model for future wells.
Stop 4: The Altona Flats well field in eastern New York hosts wells that were completed in the Cambrian Potsdam Sandstone or in Mesoproterozoic metamorphic rocks below. We will characterize 2 of these wells using modern geophysical tools.
