- The Holocene (/ˈhɒl.əsiːn, -oʊ-, ˈhoʊ.lə-, -loʊ-/) is the current geological epoch. It began approximately 9,700 years before the Common Era (BCE) (11,650 cal years BP, or 300 HE). It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.
- Humptulips-Grass Creek Wildlife Area Unit (wdfw.wa.gov)
The Humptulips-Grass Creek Unit is located in North Bay at the confluence of the Humptulips River, Grass Creek, and Grays Harbor. No maintained trails exist, and the best access is by boat or by the adventuring brush buster. This area is a popular waterfowl hunting and fishing site and has excellent birding opportunities. The unit is managed for tidal channel and estuary preservation in North Bay, salmon recovery, and waterfowl habitat.
