LAKE MECATINA – Quebec, Canada – “Stratified circular feature”

Type: Stratified Circular Feature
Diameter: ~6.4 Km
Location: North of St. Lawrence River, Quebec N 50° 49.5’ W 59° 25.1’

A geological study revealed the Mecatina structure is NOT a meteorite impact crater; rather, it is the result of multiple folding episodes of the bedrock, which is Grenville gneiss, with subsequent erosion and then recent glacial modification. It is classified as a “Stratified Circular Feature”. (a mosaic of approximately 22 individual aerial photographs and shows the lake and the region that surrounds it) – courtesy Gerencher

Lake Mecatina is located on the north shore of the St. Lawrence River in Quebec.

The 4000-foot diameter lake in the center of Mecatina crater has a compelling circular shape. The image below is a mosaic of approximately 22 individual aerial photographs and shows the lake and the region that surrounds it. North is to the top. The black on the image is water, the gray is forest, and the light tones are lichen, which is known in the area as “caribou moss.”

A similar structure is found near Parry Sound Ontario, Lakes McGruther & Dell, Ontario

The Mecatina study was funded by a grant from NASA (grant NSF-473), (Gerencher 1965)
