- Old Coast, New Coast: Sausalito, California (hakaimagazine.com)
Richardson Bay in Sausalito, California, is many things: a floating neighborhood of over 250 domiciles, an icon of the 20th-century counterculture movement, and a place to buy expensive art. It’s a place people write about and sing about, although none have composed the opera. Yet. (Proposed title: Raucous-ito.)
- Limestone (Wikipedia)
Limestone (calcium carbonate CaCO3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life.
