- Bald Hill is a 737-foot (225 m) hill in Snohomish County, Washington. The Skykomish River once flowed north of the hill but at some point in recent geologic history was diverted to its present course on the south side of the hill, moving the confluence with the Snoqualmie River (creating the Snohomish River) several miles upstream. In 1952, most of Bald Hill and adjacent Devils Butte were Washington State Forest land. As of 2016, Devils Butte is part of Lord Hill Regional Park, and the Bald Hill area was still listed by Washington State Department of Natural Resources as State Forest Trust, formerly Forest Board Trust land.
- Paleogene (Wikipedia)
The Paleogene (IPA: /ˈpeɪli.ədʒiːn, -li.oʊ-, ˈpæli-/ PAY-lee-ə-jeen, -lee-oh-, PAL-ee-; also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period and system that spans 43 million years from the end of the Cretaceous Period 66 million years ago (Mya) to the beginning of the Neogene Period 23.03 Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognized as a formal stratigraphic term, “Tertiary” still sometimes remains in informal use. Paleogene is often abbreviated “Pg” (but the United States Geological Survey uses the abbreviation Pe for the Paleogene on the Survey’s geologic maps).
