The Climbing Rangers at Mount Rainier National Park were authorized to wear this style of hat as part of their official park service uniform. The hat is styled after those worn by mountaineers. In the 1930s Mount Rainier hosted a series of Silver Ski races and the 1935 Winter Olympic Ski Trials. The pins on this hat highlight these races and the comradery that existed between the nations represented at the Ski Trials, such as the pin with the ice axe from Val Gardena and the silver ski pin with Rainier National Park.
