- Rockhounding Saddle Mountain Washington For Petrified Wood (rockseeker.com)
Saddle Mountain, a remote and rocky ridge located in central Washington. These hills rise to 2700 feet and offer stunning views of the desert landscape and the Columbia River below. But that’s not all – the fossilized wood on these rugged hills contains a record of the area’s geological history. Petrified or opalized wood is the official gemstone of Washington, and Saddle Mountain is a treasure trove for rock enthusiasts who love agatized wood.
- Star system (Wikipedia)
A star system or stellar system is a small number of stars that orbit each other, bound by gravitational attraction. A large group of stars bound by gravitation is generally called a star cluster or galaxy, although, broadly speaking, they are also star systems. Star systems are not to be confused with planetary systems, which include planets and similar bodies (such as comets).
