Hills in the Puget Lowland, between the Cascades and the Olympic Mountains, including the entire Seattle metropolitan area, are generally between Шаблон:Convert and rarely more than Шаблон:Convert above sea level. Hills are often notable geologically and for social reasons, such as the seven hills of Seattle.

Formation

The Puget Lowland lies between the Cascades and Olympic Mountains and once contained a plateau of glacial till not usually more than Шаблон:Convert above sea level.[1][2][3] The plateau, "the most prominent single landform of the entire region",Шаблон:Sfn was dissected by glacial outwash, forming present-day landforms: rivers, creeks and streams; glacial lakes such as Lake Washington; and numerous kettle lakes, and Puget Sound itself. High points on the plateau remain, most of which are a drumlin (rocky glacial debris), or a bedrock intrusion that predated glaciation. Hills above 500 feet are considered exceptional.Шаблон:Efn

Notable lowlands hills

Hills are glacial deposits unless otherwise noted. King, Pierce and Snohomish Counties run up to the crest of the Cascades where their high points reside; therefore, the Cascades and attached foothills are excluded. Likewise for Thurston County in the Mount Rainier area, and Mason County's Olympic Mountains foothills.

Island County

Whidbey Island and Camano Island are islands in Puget Sound and form the bulk of Island County.

Kitsap County

Шаблон:Main The Blue Hills of the Kitsap Peninsula are unusual in that they are composed of basalt bedrock, not glacial till.Шаблон:Sfn

Low mountains

The Issaquah Alps Bellevue, Issaquah and Newcastle on the Eastside are considered part of the Cascades foothills by many authors.Шаблон:Efn They are basalt intrusions possibly related to the Blue Hills of the Kitsap Peninsula. Highest point Tiger Mountain summit, Шаблон:Convert.

The Anacortes Community Forest Lands contain several peaks over Шаблон:Convert high, including the Fidalgo Island high point, Шаблон:Convert Mount Erie.

Mason County's Olympic Mountains foothills are called the Satsop Hills.
