Dunsmuir Mott Airport — Mount Shasta, California
Dunsmuir Mott Airport (FAA Identifier: 1O6) is a public-use general aviation airport located approximately 3 miles southeast of the city of Mount Shasta in Siskiyou County, California. Situated at an elevation of 3,258 feet above sea level in the shadow of the iconic 14,179-foot Mount Shasta volcano, this high-country airfield serves the aviation needs of the northern Sacramento Valley region and the greater Mount Shasta–Dunsmuir corridor.
The airport features a single asphalt runway — Runway 14/32 — measuring 3,500 feet in length and 60 feet in width, which accommodates single-engine and light twin-engine piston aircraft. With a traffic pattern altitude of approximately 4,258 feet MSL, pilots approaching from the south navigate terrain rising sharply to the east and north. The field is uncontrolled (no tower), operating under standard traffic advisory practices on CTAF frequency 122.8 MHz. There is no instrument approach procedure at Dunsmuir Mott Airport, making visual meteorological conditions essential for safe operations, particularly given the region's periodic mountain wave turbulence and winter snowfall.
The airport is owned and maintained by the City of Dunsmuir, which lies roughly 1.5 miles to the south of the facility. It is named in honor of the Mott family, longtime Siskiyou County residents who contributed significantly to local civic and agricultural development. The facility plays an important role in regional connectivity, providing air access to a part of Northern California that is more than 60 highway miles from the nearest commercial air service at Redding Municipal Airport (RDD), which lies to the south along Interstate 5.
Dunsmuir Mott Airport has no fixed-base operator (FBO) on site, though self-service 100LL avgas is available via credit card pump. Aircraft tie-down spaces are available at no charge for transient pilots, and there is a small pilot lounge adjacent to the ramp area. The absence of a dedicated FBO means pilots should plan fuel stops carefully — Redding Municipal Airport to the south and Montague-Yreka Rohrer Field (1O5) to the north, approximately 35 miles away, offer more comprehensive ground services.
The surrounding landscape makes Dunsmuir Mott Airport particularly popular with private pilots exploring Northern California's wilderness areas. The airport serves as a gateway to Castle Crags State Park, the Trinity Alps Wilderness, and the McCloud River fly-fishing corridor. Hikers, hunters, and anglers frequently use the airport to reach trailheads and recreation areas that would otherwise require several hours of mountain driving from the Sacramento Valley. The airport also supports aerial fire observation and light cargo operations during the busy summer wildfire season in the Shasta-Trinity National Forest.
Siskiyou County's general aviation network includes several companion airports: Montague-Yreka Rohrer Field to the north, Weed Airport (O46) approximately 12 miles northwest of Mount Shasta, and Shasta Lake Area Airport (O41) to the south. Together, these facilities form a loose network supporting agricultural operations, emergency medical access, and recreational flying across one of California's most sparsely populated regions.
Pilots planning a visit to Dunsmuir Mott Airport should consult current NOTAM (Notice to Air Mission) information via the FAA's NOTAM system, as temporary flight restrictions near Mount Shasta are periodically issued during wildfire suppression operations. Density altitude is a critical consideration at this field — on summer afternoons, effective density altitude can exceed 6,000 feet, significantly degrading aircraft performance, particularly on takeoff from the relatively short 3,500-foot runway. Thorough weight-and-balance calculations and conservative departure planning are strongly advised.
For more information about Dunsmuir Mott Airport or to verify current fuel availability and facility status, contact the City of Dunsmuir public works department. The airport identifier 1O6 (numeral one, letter O, numeral six) should be used when filing flight plans or requesting weather briefings from 1800wxbrief or ForeFlight.

Frequently Asked Questions — Dunsmuir Mott Airport, Mount Shasta, California
Dunsmuir Mott Airport's FAA identifier is 1O6 (one-Oscar-six). The airport has a single asphalt runway, designated Runway 14/32, which is 3,500 feet long and 60 feet wide. The field sits at an elevation of 3,258 feet MSL in Siskiyou County, roughly 3 miles southeast of Mount Shasta city. There is no control tower; pilots use CTAF 122.8 MHz for traffic advisories. No instrument approach procedures are published for 1O6, so flight planning should account for visual-only operations.
Dunsmuir Mott Airport offers self-service 100LL avgas via a credit card-activated pump — no Jet-A is available. There is no full-service FBO at the field. Transient tie-downs are provided at no charge, and a small pilot lounge is accessible on the ramp. For more comprehensive services including maintenance, oil, and Jet-A, pilots should plan a stop at Redding Municipal Airport (RDD), located approximately 60 miles south on I-5, or Montague-Yreka Rohrer Field (1O5) roughly 35 miles to the north.
Density altitude is a serious safety concern at Dunsmuir Mott Airport. With a field elevation of 3,258 feet and summer temperatures frequently exceeding 90°F in the Mount Shasta valley, effective density altitude on afternoon departures can exceed 6,000 feet or more. The 3,500-foot runway offers limited margin for heavily loaded aircraft under these conditions. Pilots are strongly advised to perform density altitude calculations before every departure, consider early-morning departures when temperatures are cooler, and apply conservative weight-loading. Mountain wave turbulence near Mount Shasta (14,179 ft) is also a periodic hazard requiring awareness of upper-level wind forecasts.
Dunsmuir Mott Airport is an excellent base for exploring Northern California's wilderness. Castle Crags State Park, featuring 6,500-foot granite spires, is less than 10 miles south via I-5. The McCloud River — a renowned wild-trout fly-fishing stream designated as a California Wild Trout water — is accessible within 20 miles east. The Shasta-Trinity National Forest, which spans over 2.2 million acres, surrounds the Mount Shasta area and offers hundreds of miles of hiking trails. The airport also sees traffic from hunters accessing Siskiyou County deer and bear zones in autumn, significantly reducing drive time from the Sacramento Valley compared to the 4-hour car trip from Sacramento.
The Mount Shasta–Yreka corridor is served by several general aviation airports. Weed Airport (O46), roughly 12 miles northwest of Mount Shasta city, has a 3,800-foot runway and similar services to Dunsmuir Mott. Montague-Yreka Rohrer Field (1O5), approximately 35 miles north near Yreka, has a longer 6,002-foot primary runway and better accommodates larger aircraft. Redding Municipal Airport (RDD), 60 miles south, is the nearest facility with commercial airline service (via United Express), instrument approaches, and full FBO services. For pilots flying into Northern California's Cascade Range region, Dunsmuir Mott Airport (1O6) offers the closest air access to the Dunsmuir–Mount Shasta community and Castle Crags area specifically.
