- The Carboniferous (/ˌkɑːrbəˈnɪfərəs/ KAR-bə-NIF-ər-əs) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period 358.9 million years ago (mya), to the beginning of the Permian Period, 298.9 mya. In North America, the Carboniferous is often treated as two separate geological periods, the earlier Mississippian and the later Pennsylvanian.
- Eagle Island Wildlife Area Unit (wdfw.wa.gov)
The Eagle Island Unit is located on the North Fork Lewis River, east of the town of Woodland. The area is largely a forested floodplain comprised of mature conifer and deciduous trees and dense vegetation, but a large meadow is on the downstream end of the island. The management objective for the unit is to provide riparian and side-channel habitat for salmonids, as well as habitat for black-tailed deer, waterfowl, and songbirds.
