- Seattle Neighborhoods: Madison Park — Thumbnail History (historylink.org)
The Madison Park neighborhood of Seattle is situated on the western shore of Lake Washington. The Duwamish peoples who originally inhabited it called it “Where One Chops.” The Duwamish shared the forested banks, swamps, and inlets with bear, deer, otter, and mink. After Seattle was founded in the 1850s, Madison Park became a favorite picnic and recreational area. Judge John J. McGilvra (1827-1903), the area’s first developer, purchased land and opened Madison Street at his own expense in 1864-1865. Today Madison Park is an affluent, end-of-the-carline residential district on Lake Washington which has a small, elegant shopping area.
- Extrusive rock (Wikipedia)
Extrusive rock refers to the mode of igneous volcanic rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff. In contrast, intrusive rock refers to rocks formed by magma which cools below the surface.
