- 14,000 years ago Maplewood was covered by a mile-high glacier. As the climate warmed, the glacier retreated leaving the landforms we see today. Ancient pollen grains in lake sediment help scientists piece together a timeline of the plant communities that followed the glaciers.
- Farallon Plate (Wikipedia)
The Farallon Plate was an ancient oceanic plate. It formed one of the three main plates of Panthalassa, alongside the Phoenix Plate and Izanagi Plate, which were connected by a triple junction. The Farallon Plate began subducting under the west coast of the North American Plate—then located in modern Utah—as Pangaea broke apart and after the formation of the Pacific Plate at the centre of the triple junction during the Early Jurassic. It is named for the Farallon Islands, which are located just west of San Francisco, California.
