- 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.
- Fort Flagler (wa100.dnr.wa.gov)
History buffs know that western Washington has not only a rich natural history, but also a military history that spans more than a century. Fort Flagler State Park is a piece of Washington’s historical first line of defense against maritime threats to metropolitan areas of Puget Sound. The fort was constructed in 1897 and was active until 1953. Many of the fort’s original buildings and artillery batteries are remarkably well preserved and free to explore, and several of the original officers’ houses can be rented for the night. In the summer, visitors can also take a volunteer-guided tour of the gun emplacements and other historic sites for a small donation. Perched on high bluffs and surrounded on three sides by water, the park offers panoramic views as well as a perfect vantage point for observing ship traffic into and out of Puget Sound.
