- The Mississippian (/ˌmɪsɪˈsɪpi.ən/ miss-ə-SIP-ee-ən, also known as Lower Carboniferous or Early Carboniferous) is a subperiod in the geologic timescale or a subsystem of the geologic record. It is the earlier of two subperiods of the Carboniferous period lasting from roughly 358.9 to 323.2 million years ago. As with most other geochronologic units, the rock beds that define the Mississippian are well identified, but the exact start and end dates are uncertain by a few million years. The Mississippian is so named because rocks with this age are exposed in the Mississippi Valley.

The National Nordic Museum (previously Nordic Heritage Museum and then Nordic Museum) is a museum in the Ballard neighborhood of Seattle, Washington, United States, dedicated to the Nordic history, art, culture, and the heritage of the area’s Nordic immigrants. It was founded in 1980 as the Nordic Heritage Museum, moved into a permanent, purpose-built facility in 2018 named the Nordic Museum, and was designated as the National Nordic Museum in 2019. The museum serves as a community gathering place and shares Nordic culture by exhibiting art and objects, preserving collections, and providing educational and cultural experiences from Danish, Finnish, Icelandic, Norwegian and Swedish Americans. The geographical region covered by the Museum includes the entire Nordic region (Denmark, Finland, Iceland, Norway, Sweden, Estonia, the regions of the Faroe Islands, Greenland, and Åland, and the cultural region of Sápmi).
