The Raquette River has many dams; Potsdam itself has two. Two dams up the river is Hannawa Falls, where Route 56 crosses the Raquette. Next to the dam is a trailhead for a trail down along the river to the Sugar Island dam (which I'll walk when the weather gets warmer, and record for Jigidi). At the trailhead, there's also a path down to the base of the dam, which is somewhat unusual, and provides this view.

The reddish stone is Potsdam Sandstone, which was quarried here in the 19th and early 20th centuries. Wikipedia says:

"In the 19th century, Potsdam Sandstone was highly regarded as a building material. There was extensive quarrying for Potsdam Sandstone in the Potsdam area, beginning in 1809. Properties of the rock that give it value as a building material include high compressive strength, attractive reddish coloring, and resistance to weathering. The rock also was said to be 'soft and easy to carve' when freshly quarried but 'extremely hard' and 'weather-resistant' after exposure to the air, but modern geologists suggest that this is a misconception. Potsdam Sandstone resists spalling when exposed to fire, making it highly suitable for use as a refractory for lining iron furnaces.

Local sandstone was used for many buildings in Potsdam, as well as for purposes such as gravestones and sidewalks. Buildings in other cities constructed with this rock include portions of Canada's Parliament Buildings (original Centre Block and Library of Parliament) in Ottawa, and the Cathedral of All Saints in Albany, New York. Potsdam Sandstone and its stratigraphic equivalents also have been quarried for use as building stone at several sites in Quebec."

[The material called "Potsdam Sandstone" in fact occurs over a broader area, and is found in Northern New York and northern Vermont and Quebec and Ontario.]

Snow's been gone for some time - although we keep getting reprises (it's snowing now!). Luckily, it doesn't stick. However, the cold is keeping us from doing outdoor work.


Nice view. Snow all gone? Thanks, Don.
