Hi, I'm Rachel Chow from Windermere Secondary School in East Vancouver. I'm in grade 12 and I like to read and sleep.

OPTION 3: Howe Sound Geologic History

1. Mount Garibaldi is a volcano!
   1. 
   2. About 13,000 years ago, Mount Garibaldi erupted and formed a large cone like most volcanoes. One side of the rubble was on a solid rock formation but the west side of the cone formed on a glacier. Since the ice melted, that side of the cone collapsed and that's why Mount Garibaldi doesn't look like a classic volcano.
2. You can see the remnants of the Ice Age in the mountains
   1. 
   2. The lower hills are rounded and smooth because they were ground down as glaciers flowed down Howe Sound. The higher peaks were spared by the glacier and thus, have craggy tops.
3. Black Tusk is what remains of a small cinder volcano.
   1. 
   2. Many eruptions have led to rubble piling up around the old volcano opening. Throughout the years, the actual volcano has mostly eroded so we are now left with the harder conduit.
