The stars in the Big Dipper and Little Dipper help navigators locate the North Star. Following the five stars in the Five Star Trail—the municipalities of Hempfield Township, Youngwood, South Greensburg, Southwest Greensburg, and Greensburg—takes travelers on a more northeastern tack. All five towns in the constellation partnered to create the nearly 7.8-mile trail southeast of Pittsburgh.
Following the concept of the Five Star trail these caches will be named for different constellations
Columba constellation is located in the southern sky. Its name means “the dove” in Latin. The constellation’s original name was Columba Noachi, meaning “Noah’s dove.” It was named after the biblical dove that informed Noah that the Great Flood was receding
Columba was introduced by the Dutch astronomer Petrus Plancius in the late 16th century and later appeared in German astronomer Johann Bayer’s star atlas Uranometria of 1603.
The constellation is home to the blue subgiant Phact (Alpha Columbae) and the runaway star Mu Columbae. Notable deep sky objects in Columba include the barred spiral galaxy NGC 1808 and the globular cluster NGC 1851.
