Crossover Peak

Mount MacFarlane is a 2,090-metre (6,860-foot) mountain summit located in the Cascade Mountains of southwestern British Columbia, Canada. It is situated 6 km (4 mi) north of the Canada–United States border, 3.65 km (2 mi) northwest of Slesse Mountain, and 1.4 km (1 mi) northwest of Crossover Peak, which is its nearest higher peak. Precipitation runoff from the peak drains into Slesse Creek and Pierce Creek, both tributaries of the Chilliwack River. The mountain was named to honor Royal Canadian Air Force First Lieutenant Ronald E. MacFarlane, from nearby Chilliwack, who was killed in action on December 16, 1943, at age 21. The name was officially adopted on April 7, 1955, by the Geographical Names Board of Canada.

Iron Curtain Cave is a limestone cave located in the Cheam Range near Chilliwack, in British Columbia, Canada. Discovered in 1993, the cave contains fragile speleothem formations and microbial species that have been examined in the context of antibiotic resistance. Microbiological and geological research has examined extremophile microorganisms found in the cave's low-nutrient and lightless conditions.

Chipmunk Caves are a group of small natural limestone cave openings located near the Chilliwack River, British Columbia, Canada. The caves are located along the Chipmunk Creek Forest Service Road and lie beyond a forested area, reached through a trail. The site comprises several shallow rock cavities and narrow passageways that have formed within sedimentary rock formations. The caves were initially visited by members of the Stó:lō First Nation as early as 1860. In the 1950s, oversight of the area was reportedly transferred to the National Parks Branch of Canada. The caves were primarily formed through the erosional action of subterranean water on limestone bedrock, resulting in narrow passages and shallow chambers.

Williamson Lake is a small mountain lake located below Welch Peak, near Chilliwack, British Columbia, Canada. It can be accessed by two different hiking trails, one 4 kilometers and the other 13 kilometers in length.

Slesse Creek is a tributary of the Chilliwack River in North America. It flows through Whatcom County in the U.S. state of Washington and through the Canadian province of British Columbia. The creek is known as Silesia Creek in the United States and as Slesse Creek in Canada.

Goat Mountain is a 6,844 ft summit in the Skagit Range which is a subset of the North Cascades of Washington state. It is located south of Mount Larrabee and north of Mount Shuksan in the Mount Baker Wilderness, which is managed by the Mount Baker-Snoqualmie National Forest.

Its nearest higher neighbor is Mount Chardonnay, 2.75 mi (4.43 km) to the east. The Silver Tip Mine was located on the south slope of the mountain near the 3,000 ft level. The mine produced silver and gold in the 1940s. Precipitation runoff from the mountain drains into tributaries of the Fraser River and the Nooksack River.

The Cheam Range (pronounced or ) is a mountain range in the Fraser Valley region of the Lower Mainland of British Columbia near the city of Chilliwack. The region is also a part of the Skagit Range of the Canadian Cascades and contains many rugged peaks. The western peaks in the range - Cheam, Lady, Baby Munday and Stewart, are known in areas of the Fraser Valley where they are visible, as the "Four Sisters". The eastern peaks in the range are referred to as the Lucky Four Group because of their proximity to the abandoned Lucky Four Mine; the glacier in the cirque formed by Welch and Foley is called the Lucky Four Glacier. Foley, Welch and Stewart commemorate partners in Foley, Welch and Stewart, an important contractor in early British Columbia responsible for building the Pacific Great Eastern Railway and other projects. The highest point is the Welch Peak.

Lady Peak is a mountain located just southeast of Cheam Peak in the Cheam Range near Chilliwack, British Columbia. It is west of the four peaks in the eastern portion of the range known as The Lucky Four Group or The Lucky Four, consisting of Knight, Foley, Stewart and Welch peaks. According to the Canadian Mountain Encyclopedia "From the Chilliwack area, according to Sto:lo Nation culture, Lady Peak looks like the head of a dog. This dog is the companion of the Old Woman, Cheam"Lady Peak can be summited by a route that branches off the Cheam Peak Trail.The peak was named by Arthur S. Williamson, superintendent of the nearby Lucky Four Mine, to honor Phyllis Munday, the well-known Canadian mountaineer. Williamson also named nearby Baby Munday Peak in honor of her daughter, Edith. Both toponyms were officially adopted in 1946 by the Geographical Names Board of Canada.

Mount Sefrit is a 7,191 ft (2,190 m) Skagit Range summit located three miles north of Mount Shuksan in the North Cascades of Washington state. It is situated in the Mount Baker Wilderness, which is managed by the Mount Baker-Snoqualmie National Forest. The summit offers views of Mount Shuksan, Mount Baker, and the Picket Range. Mount Sefrit's name honors Frank Ira Sefrit (1867–1950), editor and publisher of The Bellingham Herald for nearly 40 years. This mountain's name was officially adopted in 1952 by the U.S. Board on Geographic Names. Precipitation runoff from the mountain drains into the deep valleys of Ruth Creek and the Nooksack River which nearly encircle Mount Sefrit, except for Nooksack Ridge which connects it to Ruth Mountain.
