- Tradition Plateau Natural Resources Conservation Area (NRCA) is a 426-acre property owned by the City of Issaquah on the north side of Tiger Mountain within the Issaquah Alps. The site includes approximately 403 acres of forest and 23 acres of Puget Sound Energy power line right-of-way. Elevations span from roughly 200 feet near Interstate 90 to 900 feet in the southeast corner, encompassing flat plateaus, steep north-facing slopes, forested wetlands, and small lake basins at Tradition Lake and Round Lake. Coarse, gravelly glacial soils dominate the Plateau and are characterized by rapid drainage and low water-holding capacity, making drought stress one of the primary ecological concerns for tree establishment and long-term forest resilience.

A craton ( /ˈkreɪtɒn/ KRAYT-on, /ˈkrætɒn/ KRAT-on, or /ˈkreɪtən/ KRAY-tən; from Ancient Greek: κράτος kratos “strength”) is an old and stable part of continental lithosphere (the Earth’s two topmost layers, the crust and the lithospheric mantle). Having often survived cycles of merging and rifting of continents, cratons are generally found in the interiors of tectonic plates; the exceptions occur where geologically recent rifting events have separated cratons and created passive margins along their edges. Cratons are composed of ancient crystalline basement rocks covered by younger sedimentary rocks. They have a thick crust and deep lithospheric roots extending several hundred kilometres into Earth’s mantle. In simpler terms, craton is a layer of the earths crust on that has been almost unchanged through all of history. This crust consists of shields and platforms. Shields are made of basement rock and are visible, while platforms is the portion not visible made up of sedimentary rock.
