a. Extreme symmetry;
b. Exceptional depth;

The Merewether Structure (three small craters) is located north of the tree-line in Labrador, Canada, approximately 93 kilometers south-west of the Saglek Fiord. It's classified as a "Probable Meteorite Crater". The following features of this structure taken individually would not be conclusive, but together suggest that the Merewether structure may be impact related (meteorite crater remnant):</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://epod.usra.edu/archive/epodviewer.php3?oid=315776">
 a. Extreme symmetry;
b. Exceptional depth;
c. Semblance of rim which is highest at the end of   the longest diagonal;
d. A slight magnetic anomaly at the west rim;
e. The excellent agreement with Baldwin's law for explosion craters;

 f. A possible slight increase in the iron-nickel content of nearby vegetation.</DIV></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://epod.usra.edu/archive/epodviewer.php3?oid=315776">
