Limestone (80)

General Lithology:Limestone
Description:The rock adjacent to this sign originated as part of a reef, formed in a shallow sea during the Devonian Period, about 380 million years ago. Large cavities are present amongst the skeletons of sponge-like organisms that built the reef. Below the surface, these holes may be filled by water, oil, or natural gas. Rocks of this type held the oil that was discovered in 1947 at the Leduc No. 1 oil well, south of Edmonton. This discovery led to a flourishing oil industry in central and northern Alberta.
Representing:Sediment deposited in the Western Canada Sedimentary Basin during the Devonian Period, about 380 million years ago.
