- Seattle Neighborhoods: Blue Ridge — Thumbnail History (historylink.org)
In 1925, when the timberland holdings of the Puget Mill Company were sold to an eastern lumber company, the Blue Ridge community in Seattle’s northwest corner became a possibility. William E. Boeing (1881-1956), lumberman, mining entrepreneur, and airplane builder, bought up most of the company’s land overlooking Puget Sound north of the city limits to Richmond Beach. Soon the Douglas fir and cedar stands would be sacrificed for the development of the exclusive communities of Innis Arden and Blue Ridge. Today (2001), 450 homes sit on a 200-acre cul-de-sac that abuts Carkeek Park, whose western facing slopes offer spectacular views of the Puget Sound area. This acreage, bounded on the east by 12th Avenue NW and on the south by NW 100th and NW 105th streets, constitutes the upscale, covenanted community of Blue Ridge.
- Glacial erratic boulders of Island County, Washington (Wikipedia)
Glacial erratic boulders in Island County are a remnant of the Pleistocene glaciation that created Puget Sound and transformed the surfaces of what are now Island County’s main landmasses: Whidbey Island and Camano Island. South of Deception Pass, the two islands’ surfaces and beaches are completely composed of glacial till. Abundant glacial erratic boulders lie on the islands, their beaches, and under the near-shore waters.
