Crown Hill Formation is a late Ediacaran volcanic non-marine sedimentary formation in Newfoundland. [3] It's topped off with a bright red conglomerate, with silt and arkose sands of similar hue too. [4]

It's subdivided into nine facies, including (on Random Island) Brook Point, Duntara Harbour, Red Cliff (with Bluye Point Horizon subfacies') and Broad Head. [2] (on Cape St Mary's) Cross Pt Member, Hurrican Brook Mmbr [4]

Smith Sound is a zigzag 24 kilometre inner region of Trinity Bay. This sound is one of the longest portions of inshore waterways in Newfoundland, located on its north-eastern coast in the Canadian province of Newfoundland and Labrador. Bonavista Peninsula is to the north of the sound, while Random Island is to the south. The waters that make up the sound is a continuous channel that encircles Random Island, broken only by a narrow channel located at Clarenville where a causeway was built to provide access to the communities on Random Island. The channel on the south side of Random Island is North West Arm.

The Chamberlain's Brook Formation is a thin but distinctive geologic formation of dark red calcareous mudstones that crops out from Rhode Island to Massachusetts and, Nova Scotia, New Brunswick and Newfoundland. It preserves fossils, including trilobites, dating back to the lower mid-Cambrian period. Its lowermost member is the Braintree Member and the uppermost member is the Fossil Brook Member.

<span class="mw-page-title-main">Random Formation</span>

The Random Formation is a rock unit in Newfoundland dating to the early Cambrian period, dominated by tidal quartz arenites deposited in a near-shore environment, but also incorporating intertidal and open-shelf deposits, including glauconitic and mud-cracked mudstones, and red channel sandstones. It was deposited quickly and is approximately 175 m thick. The Blue Pinion Formation was originally recognized as a separate formation, but is now interpreted as an expression of the Random Formation.
