The North Shore Mountains have stood over what would become Vancouver for millions of years.
In fact, they helped form the city.
Now they've become an iconic backdrop for the city, a popular hiking destination, and offer film crews a place to shoot forest scenes.
Here are a few things you may not know about the city's massive neighbours.
1. There is no Cypress Mountain
While there is a skiing area called Cypress Mountain, there is no actual mountain with that name.
Cypress actually refers to the bowl between a few mountains. When driving up to go skiing, the name of the road even refers to this: Cypress Bowl Road.
Skiers are actually skiing on Mount Strachan and Black Mountain, with Hollyburn Mountain nearby.
2. Grouse Mountain was home to a world's first
Chairlifts are a relatively new development, less than 100 years old. The first offered a single seat to passengers looking to go uphill.
Grouse Mountain's early operators doubled that capacity with the world's first double chairlift. It opened in 1949.
3. The lost Japanese logging community
Tucked up in the Seymour River Valley 100 years ago a small Japanese settlement existed.
A 2003 dig uncovered it again, with 12 buildings rediscovered (enough to house 40 people).
The settlers who built the village made sure it included structures important to their traditional way of life, including a communal bath house, gardens and an elevated platform that may once have been a Shinto shrine.
4. The effort to cover a ski hill in snow
Anyone who watched the 2010 Winter Olympics may remember the issues there were to make sure Cypress Mountain's ski hills were covered with snow.
To make sure the Winter Olympics had snow, venue organizers tried a lot of different ways to deliver and retain the white stuff. While snow-making machines were in place, they got some help.
That included 1,000 bales of straw, firefighting helicopters airlifting snow, and trucking in snow from other (colder) areas.
5. One of the biggest trees of Canada is there
Dubbed the North Shore Giant, a Western red cedar in the Lynn Valley is the one of the biggest trees in Canada.
Likely more than 1,000 years old, the massive tree is the fourth-widest in Canada at around 5.8 m. For context, the widest tree in Canada is a 6 m wide Western red cedar located on southern Vancouver Island.
Bonus: Bus Chilling Ski Hill
For a time there was a broken-down bus in Cypress Mountain Resort's parking lot.
It was there so long the resort put up a sign that said "Bus Chilling Ski Hill."
