Geology of Caulfeild Park and the coastline of Burrard Inlet
A joint event for Lighthouse Park Preservation Society and Nature Vancouver. Membership in these societies not required.
Trip Leader: David Cook.
Registration required: Because of a need to limit the size of the group and because the event may be rescheduled due to weather, registration is required. Contact David at email@example.com to register.
Meeting time and location: 10:00 am at the anchor in Caulfeild Park, West Vancouver.

Duration: 2 to 3 hours.
Terrain and elevation gain: Uneven on rocky seaside bluffs. No trails on the rock bluffs which are where the main points of interest are located. Stairway to the sandy beach is 10 metres. Otherwise no significant elevation changes.
Length of walk: 1.5 kilometres return. Slow walking with many stops.
Nature Vancouver difficulty rating: B rating. See www.naturevancouver.ca for description of difficulty ratings.
Description of event: The unusual geology visible in the ice-smoothed rocks along the shoreline bluffs of Caulfeild Park will be explained. These rocks clearly illustrate how about 200 million years ago older rocks formed by volcanic activity offshore were brought by plate tectonics and then transformed by a process called granitization. Geologists consider this site of great value in illustrating some of the processes that took place during the formation of granitic rocks that now make up most of the North Shore mountains. The value of this site will hopefully be recognized in the future by its recognition as a Geoheritage Site. We will also observe the geology and land forms around the Outer Harbour of Burrard Inlet that are visible from Caulfeild Park. There will also be an opportunity to view the delicate coastal bluff plant ecology and the restoration work by the Lighthouse Park Preservation Society to preserve it.
