Mammoth Yosemite Airport
airport in California, United States of America
Mammoth Yosemite Airport (IATA: MMH, ICAO: KMMH, FAA LID: MMH) is a town-owned public airport seven miles (11 km; 6.1 nmi) east of Mammoth Lakes, in Mono County, California, United States. Also known as Mammoth Lakes Airport or Mammoth–June Lake Airport, it is mainly used for general aviation, but has scheduled passenger flights operated by one airline which primarily serves the airport on a seasonal basis during the winter ski season. Additional scheduled passenger service for the Mammoth area is seasonally available at the nearby Eastern Sierra Regional Airport located in Bishop, CA.
The airport had 665 passenger boardings (enplanements) in calendar year 2008, 6,157 enplanements in 2009, and 19,814 in 2010. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a general aviation airport. However, the report for 2015–2019 upgraded this status to that of a primary/non-hub commercial airport.
Facilities
The airport covers 230 acres (93 ha) at an elevation of 7,135 feet (2,175 m). Its one runway, 9/27, is 7,000 by 100 feet (2,134 by 30 m) asphalt.
In 2010 the airport had 8,285 aircraft operations, average 22 per day: 68% general aviation, 20% air taxi, 12% airline, and <1% military. Three aircraft were then based at this airport, all single-engine.
Mammoth Yosemite Airport has a terminal development master plan that will expand operations and will be able to accommodate bigger aircraft.

Why this record matters
The phrase “airport in California, United States of America” 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.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 16, 2026. The linked authority identifier is Q6745883. Authority coordinates are 37.624, -118.839. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 2008, 2009, 2010 and 2011.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
