Pikes Peak (Missouri)
Pikes Peak most likely takes its name from the taller Pikes Peak, in the Rocky Mountains.
Pinnacle Peak (King County, Washington)
First called "Mount Pete" for Pete Chorak, an early Enumclaw settler, "Pete" became misheard as "Peak", and the name "Mount Peak" received some followers. A former fire lookout built on the summit was called the Pinnacle Peak Lookout, hence the name "Pinnacle Peak" emerged. The one mile trail on the north side of Pinnacle Peak is called the "Cal Magnusson Trail" for a long time Cascade mountaineer who worked at REI for 25 years with famed American mountain climber Jim Whittaker.
