The topography of the Butternut Creek watershed was sculpted by glaciers during the
last ice age, During the glacial maximum, about 20,000 years ago, the whole area was covered by a thick ice sheet. As the ice retreated about 12,000 years ago during the
Pleistocene, Glacial Lake Newbury was formed to the west, in the present-day Syracuse area. The lake was initially dammed on its east end by the hills between the Butternut and
Onondaga Creek valleys. As meltwater filled the lake, it overflowed this ridge, turning what is now lower Butternut Creek into a large river, eventually connecting to the
Mohawk–
Hudson River river system. After the ice fully melted, the water drained northward into the Great Lakes and the
Saint Lawrence River, leaving the now dry "Syracuse channels" – a series of large breaks between the Butternut and Onondaga valleys – and a 180 foot escarpment at Clark Reservation State Park, which was once a giant waterfall fed by glacier melt. Near Jamesville, the Butternut Creek valley has carved through the limestone Onondaga Escarpment, part of the 550-million-year-old
Onondaga Formation, creating a steep and narrow gorge. The Jamesville Quarry is situated along the creek and has excavated about of the area. ==History==
