The Scale of the Federal Footprint
The Kem C. Gardner Policy Institute (March 2025) found the federal government owns 64.4% of Utah’s land area — 35.0 million of 54.3 million acres — the second-highest in the nation behind Nevada (80.1%). Tribal trust lands hold an additional 4.5%. Federal-land share ranges by county from 4.0% (Morgan) to 90.0% (Garfield). BLM and U.S. Forest Service together administer 88.5% of federal land in the state.
Cannabis is illegal on every acre of it. The Controlled Substances Act remains in force regardless of state cannabis programs.
The Statutes
- National Park Service units — 36 CFR §2.35(b)(2) prohibits cannabis
- U.S. Forest Service land — 36 CFR Part 261 has parallel prohibitions
- BLM land — federal law governs directly
- Federal misdemeanor authority — up to 6 months imprisonment and a $5,000 fine ($10,000 for organizations)
- 21 U.S.C. §844 (first-conviction simple possession) — up to 1 year and a $1,000 minimum fine
Many cases resolve as $250–$1,000 civil “infraction” tickets on first offense, but a federal-court appearance is mandatory. NPS Law Enforcement Rangers, BLM Rangers, and USFS Officers all carry full police authority. The prohibition applies equally to smoking, vaping, edibles, and any CBD product with detectable THC.
A Salt Lake patient with a valid Utah card who hikes into Canyonlands and is found in possession faces a federal charge — the Utah card has no force on federal land.

The Mighty 5 National Parks
Utah’s Mighty 5 drew 11.2 million visitors in 2024 with combined economic impact of roughly $3 billion and 26,500 jobs.
| Park | Size | 2024 Visitors |
|---|---|---|
| Zion | 146,597 acres | 4,946,592 (2nd-most visited US park) |
| Bryce Canyon | 35,835 acres | 2,498,075 |
| Arches | ~76,680 acres | ~1.5 million |
| Capitol Reef | 241,904 acres | 1.42 million (record) |
| Canyonlands | 337,598 acres | ~818,000 |
See Mighty 5 park warning for visitor-specific guidance.
National Monuments and Forests
Eight National Monuments add another 3+ million acres — Grand Staircase-Escalante (~1.87M acres after 2021 restoration), Bears Ears (1,361,849 acres), Cedar Breaks, Natural Bridges, Hovenweep, Rainbow Bridge, Dinosaur, and Timpanogos Cave. Both Grand Staircase-Escalante and Bears Ears are again under DOI review for potential reductions (April 2025).
National forests cover about 8.1 million Utah acres (USFS administers 23.4% of federal land in-state):
- Uinta-Wasatch-Cache (~2.1–2.5M acres along the Wasatch Front)
- Ashley (1,384,132 acres including the High Uintas Wilderness and Kings Peak at 13,528 ft)
- Dixie (~1.9M acres in southern Utah)
- Fishlake (~1.5M acres in central Utah)
- Manti-La Sal (~1.2–1.3M acres in the southeast)
BLM Utah manages 22.8 million acres — about 42% of the state, with roughly 18.5 million unappropriated under FLPMA (the subject of the state’s 2024 “Stand for Our Land” Supreme Court lawsuit).
Practical Guidance for Visitors
A Salt Lake patient with a valid Utah card who hikes into Canyonlands and is found in possession faces a federal charge — the Utah card has no force on federal land. Out-of-state recreational users who cross federal acreage face stacked Utah and federal exposure. Even at private lodging in Springdale outside Zion’s gate, lawful possession requires a Utah card or a 21-day non-resident card; consumption in the park is illegal regardless.
Storage best practice: child-proof container, sealed, off federal land, never within 1,000 feet of a school or other Drug-Free Zone.
Federal Employment Implications
Utah is also a major federal-employment state. Hill Air Force Base (Davis County) employs 26,893 personnel with a $2.1 billion federal payroll and $12.7 billion annual economic impact. Dugway Proving Ground (Tooele County) covers 801,505 acres — the size of Rhode Island. The Utah Test and Training Range combined with Dugway forms the largest contiguous block of overland special-use airspace in the continental United States.
All these facilities operate under the Drug-Free Workplace Act of 1988 (41 U.S.C. §81). Security-clearance positions are governed by SF-86 question 23: any cannabis use must be disclosed, current use is disqualifying, and Utah’s medical card provides no defense. ATF Form 4473 question 21.g requires denial of firearm purchase to any “unlawful user” of marijuana — a federal definition that includes Utah cardholders.
