"August 12-1918. Table Head Section, the top of the Table Head, but there is a very clear transition into the succeeding Parson sandstone. The thickness of the Table Head as here defined has a thickness of 300 feet. Richardson's first estimate is 200 feet and his second 277 feet. S. and J. made it 300 feet. Parson Sandstone. "142 It begins with greenish-black shale with only thin bands of greenish sandstone, passing into coarse greenish shale with bands of chalky sandstone 4 to 8 inches thick. About half of this green is sandy shale. Dip gradually increasing from 40° to 70° S. 60° W. 200 Crossing beds of these green sandstones some of which are chalky and others very coarse grained. Dip 50 S. 60° W. Creased out to the farther exposed ledge at low tide before we camp in Table Point Cove." 352 Fully Parson Sandstone seen. Richardson gives the thickness as 700 feet. Where did he measure this thickness? Look that up. [As Cape Head] No fault line is at all discernable, although in 1910 Torontsffel and Schuchert thought they saw one reducing the Parson sandstone to a visible thickness of 20 feet. This section was restudied the next day. See pages 144- 149.
