Abstract
MISTASTIN LAKE (55° 52′N, 63° 22′W) occupies an elliptical, east–north-east trending depression, approximately 11 by 7 miles in size, cut into moderately rugged, barren hills of Pre-Cambrian granitoid and anorthositic rocks. The presence of a butte of flat lying volcanic rocks at the western end of the lake attracted the attention of S. Duffell and F. C. Taylor in 1965. The radiometric age of a sample from this occurrence (202 million years), and the presence of a horseshoe-shaped central island of Pre-Cambrian rocks, led me to suppose that a new crater of the type of the Clearwater Lakes1 and Manicouagan2 had been discovered. This hypothesis has now been confirmed by field mapping.
