Trip Report by Leader David Cook

On Sunday, 11 August, 2019,  seventeen persons participated in a joint event for Nature Vancouver and the Cordilleran Section of the Geological Association of Canada (http://www.gac-cs.ca). (A detailed guide titled, Self-guiding Geology Tour of Stanley Park is available HERE.)

 Some of the highlights were: 

• A large glacial erratic on the beach at Third Beach
• A dyke that can be seen at low tide
• The tilted bedding of the sandstones due to the rising of the North Shore mountains.
• Concretions formed in place in the sandstones. Proof of this is bedding that can be seen passing through the concretion.
• Imperfect columnar jointing in basalts at Prospect Point that tell us that the basalt was intruded between beds of sandstone.
• Wave-cut platforms and notches formed by past and present sea-levels.
