- Coupeville — Thumbnail History (historylink.org)
Coupeville is one of Washington’s oldest towns and the seat of Island County. Situated on Whidbey Island, at Penn Cove on Saratoga Passage, the town was once the site of three permanent Lower Skagit tribal villages. Named for pioneer Thomas Coupe, it was settled by sea captains and farmers in the 1850s. Whidbey Island narrows near Coupeville; nearby Ebey’s Landing and Ebey’s Prairie share a common history. The activation of Fort Casey in 1901 spurred efforts for Coupeville incorporation in April 1910. During the Great Depression, Whidbey Island utilized government funds for building projects such as Deception Pass Bridge (1935). Many of Coupeville’s older structures survived into the 1970s and Whidbey Island support for the arts and tourism gave impetus to formation of Ebey’s Landing National Historical Reserve, the first of its kind recognized in the U.S. Continued support of tourism has preserved four blockhouses, historic buildings, and homes, and most significant, the prairie itself. Gift shops, restaurants, businesses, and boutiques in heritage buildings now line Coupeville’s Front Street and the Island County Historical Museum on Main Street interprets Whidbey Island’s past.
- Opal (Wikipedia)
Opal is a hydrated amorphous form of silica (SiO2·nH2O); its water content may range from 3% to 21% by weight, but is usually between 6% and 10%. Due to its amorphous property, it is classified as a mineraloid, unlike crystalline forms of silica, which are considered minerals. It is deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl, and basalt.
