- Recessional glaciolacustrine deposits—Silt, clayey or sandy silt, and silty sand, typically with scattered dropstones; local lenses or beds of sand or gravel. Sediments are loose or soft, massive or laminated to thinly bedded, and locally display varve-like rhythmites. Kame lake deposits locally display some soft sediment deformational features, such as tilted or deformed bedding, and were deposited in small proglacial lakes in upland ice-marginal settings, such as the Youngs Creek ice-contact complex. Upward fining sequences record waning lake sedimentation in small proglacial lakes. Upward-coarsening sequences may begin as glacial-lake deposits (units Qglr and Qgos) and grade into overlying deltaic (unit Qgod) and fluvial (unit Qgof) deposits as a result of progradation of the outwash complexes into Glacial Lake Skykomish or smaller ice-marginal glacial lake environments. Glacial Lake Skykomish sediments were deposited mostly below ~400 to 440 ft (122–134 m) elevation in the northern part of the map area (Cross Sections A and B). Broecker and others (1956) reported a radiocarbon date of 11,900 yr BP from peat overlying soft blue clay (unit Qglr) in the Lake Joy quadrangle (Dragovich and others, 2012), indicating that the area was fully deglaciated before that time.
- Blaine — Thumbnail History (historylink.org)
Blaine (Whatcom County) is located in extreme Northwestern Washington; the northern edge of its city limit is the Canadian border. The area was originally inhabited by a band of Native Americans known as the Semiahmoo. Caucasian settlers first arrived in 1858 during the Fraser River Gold Rush, when not one, but two communities named Semiahmoo were briefly established. Permanent settlement came in 1870, and eventually the two Semiahmoos became one Blaine. In the early twentieth century, Blaine was known for its canneries, including one of the largest in the country, the Alaska Packers Association, located on Semiahmoo Spit. Today (2009) the four-star Semiahmoo Resort sits on the spit, and on the northern outskirts of Blaine the Peace Arch and Peace Arch Park provide a unique and attractive gateway for those entering or leaving the United States. In 2008, the U.S. Census estimated Blaine’s population at 4,975.
