- B-type stars are very luminous and blue. Their spectra have neutral helium lines, which are most prominent at the B2 subclass, and moderate hydrogen lines. As O- and B-type stars are so energetic, they only live for a relatively short time. Thus, due to the low probability of kinematic interaction during their lifetime, they are unable to stray far from the area in which they formed, apart from runaway stars.
- Sun Lakes Wildlife Area Unit (wdfw.wa.gov)
The Sun Lakes Unit abuts Sun Lakes State Park and parts of Park, Blue, Alkali, and Lenore Lakes. Historic glacial floods in this area scoured and carved away millions of cubic feet of lava leaving behind a deep and long coulee rimmed by basalt cliffs; numerous cliffs, talus slopes, and bare rock characterize this unit.
