About this map

Issaquah and its surrounding valleys appear at a moment of significant mid-century transition, with expansion visible around the eastern shores of Sammamish Lake. The landscape is defined by the sharp rise of Tiger Mountain and Squak Mountain to the south, while the northern lowlands are punctuated by a chain of smaller water bodies including Pine Lake, Laughing Jacobs Lake, and Phantom Lake.

Industrial and transport infrastructure remains prominent, featuring the Burlington Northern railroad corridor and an Old Grade north of Grand Ridge. Cultural landmarks like the State Fish Hatchery and Sammamish Lake State Park reflect the area's development into a recreational and residential hub. Settlements such as Monohan and Inglewood sit along the lakefront, while the southwestern corner shows the rural character of Coalfield before more intensive suburbanization.
