Do I Need a Lawyer for my Yellowstone National Park Charge?
Not every Yellowstone charge requires a court appearance. But many do. Charges involving DUI, drug possession, or wildlife violations are federal offenses that typically require you to appear before a federal magistrate judge in Mammoth Hot Springs. Your Violation Notice (ticket) will have a box checked that says “Mandatory Appearance” if you are required to appear before the magistrate judge.
Ignoring your citation or pleading guilty without legal advice can lead to long-term consequences—including a permanent federal record, fines, or even a warrant for your arrest. We frequently help people who have never been charged with a crime before. If you’re unsure what to do, we’ll review your case for free and help you understand your options.

What Do I Do If I Was Charged in Yellowstone?
- Don’t ignore the Violation Notice (ticket)
- Look closely at your court date and location (usually Mammoth Hot Springs)
- Contact a federal defense attorney right away
- Ask if you can appear by Zoom or phone
- Get legal guidance before responding or entering any plea
Does Federal or State Law Apply in Yellowstone?
Most of Yellowstone National Park is in Wyoming, with small sections in Montana and Idaho. However, all of Yellowstone is governed by federal law, which makes your case significantly different from a typical state criminal case. Offenses are prosecuted by the U.S. Attorney’s Office for the District of Wyoming, and the hearings are generally held in federal court at Mammoth Hot Springs in the northern part of the Park.
Key differences:
- No jury trial: All cases are heard by a magistrate judge in a bench trial.
- Remote appearances are often permitted, especially for out-of-state visitors.
- Marijuana is still illegal under federal law, even though it’s legal in many states.
If you’ve been charged, working with a lawyer who understands these nuances is critical.
What Are Common Charges in Yellowstone?
Even a seemingly minor violation can carry serious legal consequences. These are the most common federal charges we handle:
- DUI (alcohol, marijuana, illegal drugs, or prescription drugs)
- Possession of marijuana or other controlled substances
- Approaching or disturbing wildlife
- Unlawful possession of firearms
- Entering restricted or closed areas (often referred to as “Thermal Trespass” if you entered a protected thermal area)
- Underage drinking or public intoxication
- Speeding or reckless driving
- Disorderly conduct
- Interfering with law enforcement duties, including refusing to take a breath or blood test
What are My Legal Rights If I am Charged in Yellowstone?
Being charged in Yellowstone doesn’t strip you of your Constitutional protections. You are still entitled to:
- The right to remain silent
- The right to an attorney (except if you are asked to provide a breath or blood test during an active DUI investigation)
- Protection from unlawful search and seizure
- Due process under federal law
We will evaluate your case for Constitutional violations, including improper stops, illegal searches, or Miranda rights issues.
What Happens After I’ve Been Charged?
Understanding the process can reduce stress. Here’s what to expect:
- Citation or Arrest: Issued by Park Rangers.
- Court Notice: You’ll be ordered to appear (“Mandatory Appearance”) at the federal courthouse in Mammoth Hot Springs.
- Remote Appearance: We often arrange Zoom or phone appearances when allowed.
- Bench Trial or Resolution: Cases are heard by a magistrate judge. Outcomes include dismissals, plea deals, fines, or probation.
We handle everything from evidence review to court filings and keep you informed every step of the way.
