Lighthouse Park is located in West Vancouver, BC, accessible by the #250 bus route.
The shoreline is primarily quartz diorite, the exposed roots of long-eroded volcanoes from this subduction zone’s violently volcanic past. The granite is cut with (much younger) volcanic dykes, the feeder-system for Prospect Point (Stanley Park) and Sentinel Hill (Ambleside).
Like pretty much all of the lower mainland, it is incredibly easy to find stellar examples of glacial scour from the 2 km of ice that squished and polished the region upto 13,000 years ago.
Thank you to Jo for indulging the frequent rock-stops that characterizes hiking with a geoscientist, and for posing for scale in innumerable photographs.
