- Washington State Route 542 (Wikipedia)
State Route 542 (SR 542) is a 57.24-mile-long (92.12 km) state highway in the U.S. state of Washington, serving Mount Baker in Whatcom County. SR 542 travels east as the Mount Baker Highway from an interchange with Interstate 5 (I-5) in Bellingham through the Nooksack River valley to the Mt. Baker Ski Area at Austin Pass. It serves as the main highway to Mount Baker and the communities of Deming, Kendall, and Maple Falls along the Nooksack River. The highway was constructed in 1893 by Whatcom County as a wagon road between Bellingham and Maple Falls and was added to the state highway system as a branch of State Road 1 in 1925. The branch was transferred to Primary State Highway 1 (PSH 1) during its creation in 1937 and became SR 542 during the 1964 highway renumbering.
- Mount Baker (Lummi: Qwú’mə Kwəlshéːn; Nooksack: Kw’eq Smaenit or Kwelshán), also known as Koma Kulshan or simply Kulshan, is a 10,781 ft (3,286 m) active glacier-covered andesitic stratovolcano in the Cascade Volcanic Arc and the North Cascades of Washington in the United States. Mount Baker has the second-most thermally active crater in the Cascade Range after Mount St. Helens. About 30 miles (48 km) due east of the city of Bellingham, Whatcom County, Mount Baker is the youngest volcano in the Mount Baker volcanic field. While volcanism has persisted here for some 1.5 million years, the current volcanic cone is likely no more than 140,000 years old, and possibly no older than 80–90,000 years. Older volcanic edifices have mostly eroded away due to glaciation.
