Lindeman Lake is a beautiful alpine lake next to the popular Chilliwack Lake. It is a nice hike in and back. There are several nice campsites along the west shore. If you continue past the lake, the trail will take you to Greendrop Lake.

The small larch forest and the scattered larch trees on the way to Frosty Mountain attract many people here every year, especially in autumn. Also known as Mountain Monarch, you will find a very special tree species here, the alpine larch. Some larches are over 2,000 years old. They are especially beautiful to look at in the fall, when they change their green leaf dress for a bright yellow one.

If you want to climb Frosty Mountain, it's best to start at Lightning Lake and choose the ascent from the west. This is not as steep and arduous as the climb from the east from Windy Joe. Also, you can spend a night at Frosty Creek Camp at about 1,900 meters and climb the summit the next day. With Frosty Creek flowing, this is also your closest water source. To spend the night in the backcountry, you'll need a permit that costs $5 a night per person. Also note: In winter and even in fall, Frosty Mountain can be snow covered. If you descend to the west, you should have microspikes in your backpack for this case.

If you come all the way from the Mexican border this is where your epic journey along the 2,650 miles of the Pacific Crest Trail ends. It might also be the start of your adventure if you chose to hike the National Scenic Trail southbound. It is marked with a wooden pillar monument a little south of the international boundary marker to Canada called Monument 78. As of January 25, 2025, the Pacific Crest Trail permit program to enter Canada has ended. You are only allowed to enter Canada using a designated point of entry. On the United States side, the nearest road to pick up a hiker is Hart’s Pass Road (usually passenger-vehicle accessible) which is a hike of around 30 miles south from the northern terminus. As getting to and from the northern terminus is not that easy since there are no roads, here are some helpful tipps for logistics and maps: https://www.pcta.org/discover-the-trail/backcountry-basics/pct-transportation/directions-northern-terminus-pct/

There is space for 2-3 tents for emergency situations. But be prepared: The next watersource is a difficult climb away at the Frosty Mountain glacier (small creek). Also: It can get very cold at night: -5 and snowstorm mid September (When I went there). But definitely fun and adventurous camping up there!

The fall of Hope (Hope Slide) occurred on January 9, 1965 at Hope, 135 km east of Vancouver, in the extreme southwest of Canada. The landslide was the largest in Canadian history and costed four lives, though in an almost uninhabited area. He tore from a steep slope (> 45 °) just below a ridge in the Cascade Mountains and poured into a side valley of the Coquihalla River, which flows about 10 km further at Hope in the Fraser River. As local surveys showed, 46 million cubic meters of rock and boulders crashed down a slant slope inclined at about 20 ° and remained as a huge heap of 70 meters in height and three kilometers in length. According to Albert Heim's rule of thumb, the lintel on the slide had to have a speed of over 200 km / h. The pebble avalanche completely drained a lake (Outram Lake) near the Nicolum River and moved the river. It also rolled a few miles off Highway 3 (a branch of the newly opened Trans-Canada Highway) that had to be closed for weeks.

The Hope Slide was the largest recorded landslide in Canada, apart from the similarly sized Mount Meager landslide of 2010. It occurred in the morning hours of January 9, 1965 in the Nicolum Valley in the Cascade Mountains near Hope, British Columbia, and killed four people. The rock volume caused by the landslide was estimated at 47 million cubic meters. Source: Wikipedia
