Abstract
DURING the summers of 1961, 1962 and 1963 temperature gradient measurements were made in a hole drilled in the Brent Crater1, which is thought to be of Cambrian age and is about three miles north of Cedar Lake in Algonquin Park, Ontario. This hole, which was started on March 10, 1959, and completed to 3,489 ft. on May 23, 1959, mainly passes through limestones and shales for the top 750 ft. and then through a complicated series of rocks ranging from indurated tuffs to porous breccias. By the time the first measurements were made in 1961 the hole had become blocked at a depth of 1,285 ft.
