- Ant (Wikipedia)
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists.
- Mount Persis (summitpost.org)
Mt. Persis is Mt. Index’s little sister. One might say Persis is Index’s stunted twin, for the two peaks share a lot of “facial features.” Both are steep walled on the north and east sides and both are rugged but relenting on their south and west sides. This is understandable, as both peaks are part of a granodiorite intrusion emplaced in the early Tertiary Period (50-60 million years ago).
- 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.
