Sunday August 28 - 1910 St. Johns This morning ascended Signal Hill to get a view of the harbor and the sea headlands. A fog set in and could see nothing. Ascended again in the afternoon and had a fine view. These headlands are made of regularly bedded red sandstone and conglomerates standing at 70° or steeper. In general they look like the Cambrian sandstones of southeastern Labrador but as they underlie primarily underlie the Cambrian they are of Algonkian age. These sandstones lie in broad open folds. Signal Hill is one limit of the syncline. In character they are an arkose with the feldspars unaltered, and the pieces are angular to subangular. Beneath the red sandstones are orthoquartzites and a greenish phyllite. The hills in which St. Johns is built are of the Aspidella slates. These sandy slates are hardened by pressure but are fine slates. Have some Aspidella collected near the Agriculture and Mines Building on Henry St.
