I may have seen this beach from the Lion's Gate Bridge earlier, but the first time it really registered with me was 20 years ago when I heard Wolf Bauer talk about it. But this week was the first time I've actually walked it - or watched the sun set from it!
The exposure to waves from the west must drive any loose sediment on the West Vancouver shoreline eastward and historically it probably wound up incorporated into the protruding delta of the Capilano River, which emerges into Burrard Inlet just east of the bridge. Groins (groynes, in Canadian) now organize West Vancouver's sand and gravel into pocket beaches - including the large one at Ambleside Park. The beach curves out to meet a large groyne, on the end of which stands a Squamish figure welcoming visitors to Vancouver and the Squamish's historic land.
