- Clearwater Bogs Natural Area Preserve (dnr.wa.gov)
This 504-acre preserve protects two sphagnum bog ecosystems and sheltering forested drainages, as well as one state-listed sensitive plant species-Alaska plantain. These bogs support other unusual bog plants such as Oregon anemone and deer cabbage, and common bog plants which include bog-laurel, Labrador tea, spirea and heather.
- Apparent magnitude (Wikipedia)
Apparent magnitude (m) is a measure of the brightness of a star or other astronomical object. An object’s apparent magnitude depends on its intrinsic luminosity, its distance, and any extinction of the object’s light caused by interstellar dust along the line of sight to the observer.
