- A geode (/ˈdʒiː.oʊd/; from Ancient Greek γεώδης (geṓdēs) ’earthlike’) is a geological secondary formation within sedimentary and volcanic rocks. Geodes are hollow, vaguely spherical rocks, in which masses of mineral matter (which may include crystals) are secluded. The crystals are formed by the filling of vesicles in volcanic and subvolcanic rocks by minerals deposited from hydrothermal fluids; or by the dissolution of syn-genetic concretions and partial filling by the same or other minerals precipitated from water, groundwater, or hydrothermal fluids.
- Phinney Ridge, Seattle (Wikipedia)
Phinney Ridge is a neighborhood in north central Seattle, Washington, United States. It is named after the ridge which runs north and south, separating Ballard from Green Lake, from approximately N. 45th to N. 80th Street. The ridge, in turn, is named after Guy C. Phinney, lumber mill owner and real estate developer, whose estate was bought by the city and turned into Woodland Park in 1899. Phinney’s estate had included a private menagerie, and the western half of the park became what is now the Woodland Park Zoo.
