Geologic map of the Barnes Hill talc prospect, Waterbury, Vermont
The Barnes Hill talc prospect is in northeastern Waterbury township, Washington County, Vermont, about 2.2 miles N. 35° E. of the road triangle at Waterbury Center. The deposit occurs in a body of ultramafic rock that crops out between the altitudes of 1,150 and 1,190 feet above sea level, near the crest of a broad, low ridge on a gently rolling upland of low relief. The area surveyed is about 46 acres. It is drained on the east by a small tributary of Thatcher Brook and on the west by Bryant Brook. Thatcher Brook empties into the Winooski River at Waterbury; Bryant Brook flows into the Waterbury River, a tributary of the Winooski River. Most of the area is in open pasture, with a few scattered spruce and hemlock, but along the eastern side of the property there is a dense growth of maple saplings and underbrush.
