Founded as a community to supply miners during the Turnagain Arm gold rushes of the 1890s, Girdwood was mostly a small, quiet place until the middle of the 20th century. Two events drastically altered that. The first was the establishment of Alyeska Resort along the slopes of Mount Alyeska, which became an international destination coincidental with Anchorage's civic promotion of itself as "The Air Crossroads of the World". The second was the 1964 earthquake, which devastated the original townsite located directly along the arm. Following the earthquake, most of the town moved further up the valley to a new townsite, though a few homes remained and a strip mall was later constructed along the Seward Highway. Historically dominated in the years since the resort's opening by seasonally-occupied vacation homes and seasonal activity at the resort, the opening of the Alyeska Prince Hotel during the 1990s has shifted the resort, and hence Girdwood as a whole, more towards year-round activity and a year-round economy. This has led to periodic debates about community growth and affordability of housing for resort workers, many of whom over the years have resorted to camping illegally on public lands.
