Source-derived summary

Nancy Jackson (c. 1956 – March 27, 1990) was an American mountain climber, known for her expertise on Mount Rainier and as a climbing guide. She died while taking part in the 1990 American Manaslu Expedition when she was caught in an avalanche.

Background

Jackson grew up in Moscow, Idaho; her father Melbourne L. Jackson (1915–2004) was a professor of chemical engineering at the University of Idaho, and her mother Elizabeth Ford was a daughter of Montana governor Sam C. Ford. Nancy Jackson graduated from Moscow High School in 1972 and followed in her father's footsteps, becoming an engineer.

In 1977, she earned a degree in chemical engineering from Oregon State University in Corvallis and in 1980 a master's degree from the University of Washington in Seattle. After working as an environmental engineer, Jackson later gave up her job at Weyerhaeuser to devote herself full time to climbing.

Mountain guide

Jackson moved to Federal Way, Washington where she became a mountain guide for Rainier Mountaineering Inc. She climbed Rainier more than 50 times during the 1980s and reached the summits of Denali in Alaska, and Aconcagua in Argentina, the highest peak in South America.

While working as a mountain guide, she collaborated with author Kurt Hanson on the 5th edition of Mountaineering: The Freedom of the Hills, one of the most significant guidebooks for mountaineers.

Editorial analysis

Why this record matters

The phrase “american climber” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 25, 2026. The linked authority identifier is Q126923370. None of the 1 selected statements returned an explicit reference. The first chronological checks are 1956, 1990, 1915 and 2004.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
