- Seattle Neighborhoods: Madrona — Thumbnail History (historylink.org)
Seattle’s Madrona neighborhood overlooks Lake Washington from the eastern rim of the city. Madrona’s hilly origins arise from the Vashon Glacier, which melted 40,000 years ago, leaving flood waters and ice to shape Lake Washington and other Pacific Northwest landmarks. Its first life was as a Native American hunting and fishing ground. Seattle was founded (in 1851), and from the 1880s to 1900, Madrona was overrun by loggers, stump farmers, berry pickers, and realtors. The beginning of the Madrona we know today was the introduction of the Union Trunk Line, which ran from the top of the hill at 34th Avenue and Union Street to Madrona Park and beach.
- Sirius (Wikipedia)
Sirius is the brightest star in the night sky. Its name is derived from the Greek word Σείριος (Latin script: Seirios), meaning lit. ‘glowing’ or ‘scorching’. The star is designated α Canis Majoris, Latinized to Alpha Canis Majoris, and abbreviated α CMa or Alpha CMa. With a visual apparent magnitude of −1.46, Sirius is almost twice as bright as Canopus, the next brightest star. Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The distance between the two varies between 8.2 and 31.5 astronomical units as they orbit every 50 years.
