The Rock

Nothing interesting really happened on the trail today so I’m going to talk about the rock. The rock in the park has a lot of history, it actually came from a glacier, called “glacier erratic” and I guess it just left the rock there a long long long time ago. It weighs about 50000 to 100000 pounds. it’s really hard to tell what it’s made of because it’s covered in moss! It’s probably made of limestone, diorite or granite, I’m guessing.


There are three “famous” glacial erratics near us, including the famous white rock for which the town and beach of White Rock is named. There’s one in Aldergrove. And there’s another in Coquitlam, only 8 km away (as the crow flies), which seems to be the same kind as in Harper Park (possibly granodiorite).
