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[5]
