- Mount Persis (Wikipedia)
Mount Persis is a 5,464-foot (1,665-metre) summit located in Snohomish County, of Washington state. The mountain is part of the Cascade Range and is situated in the Mount Baker-Snoqualmie National Forest. The mountain was named for Persis Gunn (1846–1898), wife of homesteader/miner Amos Gunn who started the nearby town of Index, Washington, and also named nearby Mount Index. Precipitation runoff from the mountain drains into tributaries of the Skykomish River. Topographic relief is significant as the summit rises 4,160 feet (1,270 meters) above Anderson Creek in 0.8 mile (1.3 km). The rocks of Mount Persis are volcanic in origin and are considered amongst some of the earliest expressions of volcanism in the Cascade Mountain range in Washington.

MIAPLACIDUS (Beta Carinae). In spite of intense study, some stars refuse to yield their true characters. Here is the opposite, one that seems to be about as completely understood as reasonably possible. One of the few stars of the far southern hemisphere to carry a proper name, Miaplacidus – Beta Carinae in Carina, the Keel of the Ship Argo – is also one of the brightest of the sky.
