William Jerome Whalen III (July 18, 1940 – September 28, 2006) was the 10th director of the United States National Park Service.
 He joined Park Service in 1965 as a Job Corps counselor and advanced to posts in National Capital Parks and Yosemite before becoming superintendent of Golden Gate National Recreation Area in 1972.
 His experience in the burgeoning urban parks field contributed to his appointment as director in July 1977, yet the most significant event of his tenure was President Jimmy Carter's proclamation of much Alaska wilderness as national monuments in 1978, doubling the area under NPS jurisdiction.
 Friction with park concessioners led to congressional calls for Whalen's removal in 1980, and Secretary of the Interior Cecil D. Andrus returned him to Golden Gate.
 He left the NPS in 1983.
The Eskimo potato is a type of edible plant that grows in the northern areas of Canada and Alaska.
 It can be used in the state's famous Alaskan potato and egg breakfast tacos.
 The plant's scientific name is variously attributed as either "Claytonia tuberosa" (Inuit: "oatkuk") or "Hedysarum alpinum" (Inuit: "mashu").
 Both species have a range in the northern area of North America, have edible roots, and have been documented to have been used as a food source by Inuit peoples.
 Due to its nutritional qualities, the eskimo potato is one of many edible foods listed in survival guides, such as the US Army's field manual "Survival", and is used in modern times to subsist in nature; for instance, Christopher McCandless used the plant as a food source while he survived in the Alaska wilderness.
 However, while the tubers are edible, it is suspected that the ingestion of seeds from this plant caused McCandless' death.
