Squak Mountain is the second most westerly mountain of the Issaquah Alps mountain chain in Washington state. It is situated between Cougar Mountain to the west and Tiger Mountain to the east. Interstate 90 parallels the base of the north side of the mountain. Much of the Squak Mountain watershed drains into Lake Sammamish. Most of the mountain is protected by Squak Mountain State Park and the Cougar/Squak and Squak/Tiger Corridors of King County. Squak Mountain actually consists of three major peaks: the Central Peak (Elevation 2024 feet), the West Peak (Elevation 1995 feet), and the Southeast Peak (Elevation 1673 feet). The name "Squak" comes from the Southern Lushootseed placename /sqʷásxʷ/, which is also the source of the name Issaquah Creek and the city of Issaquah. History Squak Mountain first appears in the history of European settlement after the discovery of coal on the mountain in 1859. This helped fuel the establishment of the first commercial coal mine in Issaquah in 1862 and in Renton in 1863. While there is no longer coal mining on Squak Mountain, the dangers posed by abandoned mines are one reason it has been preserved from development. Squak Mountain State Park was formed in 1972. The initial land grant of 590 acres to form the park was made by the Bullitt family. The initial grant was near the top and specified that the land remain in its natural state. These stipulations can still be seen today in the greater restrictions in park usage at the top of the mountain, on the original Bullitt family parcel. The remains of the Bullitt family home (just a foundation and fireplace) can be found in this original parcel. Over time, the park has expanded to its current size of 1,545-acres through the acquisition of additional parcels of land. While generally a quiet and safe park, there have been some incidents over the years: On January 15, 1953, during a heavy storm, a Flying Tiger Line DC-4 flying to Boeing field from Burbank, California, was blown off course, clipped trees near the summit and came down near a farm near the Issaquah-Hobart Road in a fiery crash that killed all on board. The fire was so intense it was four days before it burned itself out enough that rescuers could approach and recover the bodies. On May 4, 1991, Donna Barensten who suffered from dementia, disappeared while hiking with her
