Puget Sound is a complex estuarine system of interconnected marine waterways and basins located on the northwest coast of the U.S. state of Washington. As a part of the Salish Sea, the sound has one major and two minor connections to the Strait of Juan de Fuca, which in turn connects to the open Pacific Ocean. The major connection is Admiralty Inlet; the minor connections are Deception Pass and the Swinomish Channel.
Kenmore is a city in King County, Washington, United States, along the northernmost shore of Lake Washington. It is a suburban commuter town at the mouth of the Sammamish River, 12 miles (19 km) northeast of downtown Seattle and 2 miles (3.2 km) west of Bothell. The population was 23,914 at the 2020 census. Kenmore Air Harbor is the largest seaplane-only passenger facility of its kind in the United States.
Bothell is a city in King and Snohomish counties in the U.S. state of Washington. It is part of the Seattle metropolitan area, situated near the northeast end of Lake Washington in the Eastside region. It had a population of 48,161 residents as of the 2020 census.
The Sammamish River flows through north King County, Washington for about 14 miles (23 km), draining Lake Sammamish into Lake Washington. Along its course, the Sammamish River flows through Redmond, Woodinville, Bothell, and Kenmore.
Chief Seattle Council is the local council governing the scouting activities of the Boy Scouts of America in a large part of the Puget Sound and Seattle area, including almost all of the Olympic Peninsula.
The Eastside of the King County, Washington area in the United States is a collective term for the suburbs of Seattle located on the east side of Lake Washington.
A glacial erratic is a glacially deposited rock differing from the type of rock native to the area in which it rests. Erratics, which take their name from the Latin word errare, are carried by glacial ice, often over distances of hundreds of kilometres. Erratics can range in size from pebbles to large boulders such as Big Rock in Alberta.
The Seattle Fault is a zone of multiple shallow east–west thrust faults that cross the Puget Sound Lowland and through Seattle in the vicinity of Interstate Highway 90. The Seattle Fault was first recognized as a significant seismic hazard in 1992, when a set of reports showed that about 1,100 years ago it was the scene of a major earthquake of about magnitude 7 – an event that entered Native American oral traditions. Extensive research has since shown the Seattle Fault to be part of a regional system of faults.
Cascadia College is a public community college in Bothell, Washington, on a shared campus with the University of Washington Bothell. Established in 2000, Cascadia was built to serve the cities of Bothell, Woodinville, Kirkland, Kenmore, Duvall, Carnation, Sammamish, Redmond and other smaller communities within the greater Seattle area.
The term seven hills of Seattle refers unofficially to the hills the U.S. city was built on and around, though there is no consensus on exactly which hills it refers to. The term has been used to refer to several other cities, most notably Rome and Constantinople.
The Withrow Moraine and Jameson Lake Drumlin Field is a National Park Service–designated privately owned National Natural Landmark located in Douglas County, Washington state, United States. Withrow Moraine is the only Ice Age terminal moraine on the Waterville Plateau section of the Columbia Plateau. The drumlin field includes excellent examples of glacially-formed elongated hills.
Boulder Park National Natural Landmark, of Douglas County, Washington, along with the nearby McNeil Canyon Haystack Rocks and Sims Corner Eskers and Kames natural landmarks, illustrate well-preserved examples of classic Pleistocene ice stagnation landforms that are found in Washington. These landforms include numerous glacial erratics and haystack rocks that occur near and on the Withrow Moraine, which is the terminal moraine of the Okanogan ice lobe.
Julie Speidel is a sculptor from Seattle, Washington. She is the daughter of author Bill Speidel and stepdaughter of oceanographer Robert S. Dietz. She is also part owner of the Seattle Underground tours company, Bill Speidel Enterprises.
Glacial erratic boulders of Snohomish County are large glacial erratic boulders of rock which were moved to Snohomish County, Washington by glacial action during previous ice ages.
The Lawrence Lake erratic is a glacial erratic boulder near Lake Lawrence in Thurston County, Washington. The boulder is about 15 feet (4.6 m) tall. Lake Lawrence itself was formed when the Vashon Glaciation created most of the topography seen in the Puget Sound region. The erratic is one of the southernmost in the Puget Sound region, near the limit of the Yelm lobe of the Vashon Glacier in the Rainier area.
Many glacial erratic boulders can be found in the Puget Sound region as far south as the Yelm area where the Puget Lobe of the glacier reached its maximum extent.
Glacial erratic boulders in Island County are a remnant of the Pleistocene glaciation that created Puget Sound and transformed the surfaces of what are now Island County's main landmasses: Whidbey Island and Camano Island. South of Deception Pass, the two islands' surfaces and beaches are completely composed of glacial till. Abundant glacial erratic boulders lie on the islands, their beaches, and under the near-shore waters.
The Vashon Glaciation, Vashon Stadial or Vashon Stade is a local term for the most recent period of very cold climate in which during its peak, glaciers covered the entire Salish Sea as well as present day Seattle, Tacoma, Olympia and other surrounding areas in the western part of present-day Washington (state) of the United States of America. This occurred during a cold period around the world known as the last glacial period. This was the most recent cold period of the Quaternary glaciation, the time period in which the arctic ice sheets have existed. The Quaternary Glaciation is part of the Late Cenozoic Ice Age, which began 33.9 million years ago and is ongoing. It is the time period in which the Antarctic ice cap has existed.
Hills in the Puget Lowland, between the Cascades and the Olympic Mountains, including the entire Seattle metropolitan area, are generally between 350–450 feet (110–140 m) and rarely more than 500 feet (150 m) above sea level. Hills are often notable geologically and for social reasons, such as the seven hills of Seattle.
