- Geologic Map of the East Half of the Bellevue South 7.5’ x 15’ Quadrangle, Issaquah Area, King County, Washington
The Issaquah area includes several of the most outstanding geologic features of the eastern Puget Lowland region. Folds have warped thousands of meters of Tertiary sedimentary and volcanic rocks. Several hundred meters of both glacial and postglacial sediment have accumulated in a deep glacial trough, which is now partly occupied by Lake Sammamish but which was previously the conduit for massive volumes of meltwater during ice-sheet occupation and retreat. The eastern projection of an east-west-oriented crustal structure, which reflects Tertiary through Holocene fault displacement, extends across the eastern part of the map area.
- Green Lake Park (Seattle) (historylink.org)
Green Lake Park is a 323-acre park located in north Seattle, adjacent to Woodland Park. Famed landscape architect John Charles Olmsted included a boulevard around Green Lake in his 1903 plan for Seattle’s park and boulevard system. The Board of Park Commissioners acquired the lake and surrounding land by 1908 and hired Olmsted to create plans for the park in 1908 and 1910. Over the years, the park evolved from a boulevard, to a rustic lakeshore park, to a more formalized park with numerous annual events held on the lake, to a park with fewer water-based events, but a highly used pathway circumnavigating the lake. It is one of the most popular parks in the state.
