Sumas Mountain

The Swift Creek Landslide is an active, slow-moving landslide located in western Washington, USA, due east of Everson on Sumas Mountain. Asbestos laden sediment originating from the landslide has recently generated much interest in this area. Asbestos is a known carcinogen. EPA sampling has documented asbestos in sediments in Swift Creek and in downstream Sumas River. Average asbestos levels in Swift Creek dredged material exceed the level that, in construction materials, triggers worker safety requirements and material handling and disposal regulations.

Independence County was a proposed county to be created from the northwest corner of Whatcom County, Washington. The proposal had the most momentum in the county elections of 1993, when secessionist interests won a majority of votes on the County Council. The Independence County proposal, like other county secession proposals in Washington, was organized by construction and development interests (under the banner of property rights), hoping that a separate county would redefine county zoning and land use plans to encourage new development. Proponents of the new county took advantage of rural landowners' perception of tax flow: that property taxes had increased unreasonably in order to foot the bill for infrastructure development in the county seat of Bellingham, Washington. This assertion was bolstered by studies on three of Washington's county creation proposals (including Independence) undertaken by UW Professor Richard Zerbe, but refuted by Whatcom County Assessor Keith Wilnauer. In 1994 the Independence County movement was based in Deming, Washington, organized by Doug Howard, a preacher, retail landowner, and mortgage lender. The Independence movement had ties to the Wise Use Movement, and anti-environmental interest group. The Independence movement also had ties to other county secession movements in Washington including Freedom, Pioneer, and Skykomish county proposals. Petitions to propose that Independence County be created were circulated around the proposed area between 1993 and 1994. Many signatories believed that they were signing an initiative to be placed on an upcoming ballot, but it was only a petition to the legislature. After the Washington State Public Disclosure Commission secured a disclosure hearing into the lobbying actions and finances of the organized Cedar County, Washington movement, the Independence County organized movement (as well as those of other Washington county secession movements) shut down in 1994.

Nooksack ( NUUK-sak) is a city in Whatcom County, Washington, 8 km (5.0 mi) south of the border with Canada. The population was 1,338 at the 2010 census. Despite the name, it is actually located right next to the upper stream of the Sumas River, and is 2 km (1.2 mi) northeast of the nearest bank of the Nooksack River. Nooksack shares Nooksack Valley School District with the nearby Sumas and Everson. The town is just a handful of buildings built around the State Route 9 highway that runs through it, and contracts the police and sewer services through the adjacent City of Everson. The post office lost its official status in 1992 (now a department of neighboring Everson) and the USPS has since closed the remote office, but the building still exists across from a small city park. Other noticeable remains are the two filling stations and several churches. It has no major geographic features except two small creeks that drains into the Sumas River on the edge of town, near a cemetery containing many old graves.

Huntingdon is a community within Abbotsford, British Columbia, Canada. It is located immediately north of the Canada–US border, and is the location of the Sumas-Huntingdon Border Crossing. The main road through the community is Highway 11. The name of the community is also the present name of the border crossing connecting to Sumas, Washington. It is named for Collis P. Huntington, a Union Pacific Railroad railway executive who helped connect the Canadian Pacific Railway line to US Lines. The CPR wanted direct BC connection to Seattle, south, and onto California so it built a bridge at Mission and rail line across Matsqui Prairie to connect with the Seattle, Lake Shore and Eastern Railway. The Northern Pacific Railway, Union Pacific Railroad and Milwaukee Roads built lines to Sumas, with an eye of coming to Vancouver, but never crossed the border in the end. BC Electric Railway and Great Northern did build to Huntingdon and into the eastern Fraser Valley. Member of Parliament for Abbotsford, Ed Fast, is spearheading an effort to have the border crossing renamed to Abbotsford.
