Yosemite Federal Holding Overview
The research file traces this facility to a Mariposa County Grand Jury report that listed "Yosemite National Park Federal Holding Facility" as one of four detention facilities within Mariposa County. The same research notes that the Grand Jury did not visit it and that current official NPS detention-specific address, phone, capacity, and public inmate-lookup details were not located. That gap controls the page. The facility should be described as a short-term federal holding setting associated with Yosemite National Park law-enforcement custody, not as a public county jail.
Yosemite National Park creates custody questions that do not fit a simple county jail search. The park has federal jurisdiction, and a person arrested in or around the park may be cited, released, held briefly, booked into the Mariposa County Adult Detention Facility, transported, or routed through federal court depending on the facts and agency decisions. Official Mariposa booking-report snippets can show Yosemite National Park as an arrest agency or Yosemite as a jurisdiction when someone is booked locally. That does not mean every Yosemite arrest enters the county jail system.
Yosemite Facility Public Details
No current official NPS page with a detention-specific street address, public phone number, capacity, visiting schedule, mail process, or commissary process was located in the research. Because those facts were not found, they should not be invented or borrowed from the county jail, BOP, or NPS visitor app pages. The official Yosemite app page is useful only to distinguish visitor information from custody lookup. It is not a detention locator.
The absence of a public roster is not proof that no one was detained. It means the public search path depends on custody stage. If the person is booked into the Mariposa County jail, county tools can help. If the person remains in federal pretrial custody, federal court, counsel, or U.S. Marshals-related channels may be more relevant. If the person is sentenced and received by BOP, the BOP locator becomes useful.
Yosemite Federal Custody Lookup
Start by separating local booking from federal custody. The Mariposa County Daily Booking Report covers people arrested and booked into the Adult Detention Facility during the last 24 hours. It can help only if the Yosemite arrest resulted in a local county booking. If no local booking appears, the person may have been cited, released, not yet booked, transported, held federally, booked elsewhere, or handled through a federal court path.
- Check the Mariposa Daily Booking Report if the arrest was recent and local booking is possible.
- Call the Mariposa County Adult Detention Facility at 209-966-3616 only to confirm county jail custody or bail basics.
- Use VINE if the person may be in a participating jail or prison system.
- For federal sentenced custody, search the BOP inmate locator.
- For federal pretrial matters, use federal court, attorney, or appropriate federal law-enforcement channels because BOP may not show the person yet.
- For immigration custody, use ICE ODLS rather than county or BOP tools.
The Federal Bureau of Prisons inmate locator is a useful federal custody source once BOP custody applies.
The BOP locator is not a live Yosemite holding-cell roster and may not show federal pretrial custody before BOP designation.
Yosemite Holding Contact Limits
The facility map could not supply a verified detention-specific NPS address or phone number for the Yosemite federal holding facility. For that reason, the contact card should state the research gap rather than publish guessed details. The Mariposa County jail phone appears below only as the local booking fallback, not as a Yosemite federal holding-facility number.

Yosemite Federal Visit Questions
No public Yosemite federal holding visiting schedule was located. That means the county jail housing-block visiting table should not be copied onto this facility. Short-term federal holding often is not a family visitation setting at all, and a person may be released, cited, transported, taken to court, or booked into another facility before public visit planning is possible.
| Custody Stage | Visit or Contact Path | Important Limit |
|---|---|---|
| Booked into Mariposa County jail | Use county jail visit rules after confirming housing | Applies only after local booking |
| Short-term federal hold | Use attorney or federal agency contact | No public schedule located |
| Federal pretrial detention | Check court and counsel channels | BOP may not list the person yet |
| BOP sentenced custody | Use BOP facility rules after locator result | Yosemite page will not control visiting |
| ICE custody | Use ICE ODLS and ICE facility rules | No ICE detention center in Mariposa located |
Yosemite Federal Mail Money
No detention-specific mail, phone, commissary, or money-deposit process was located for a Yosemite federal holding facility. Do not send mail or funds based on Mariposa County jail mail scanning, NCIC calling, mycarepack, or county commissary rules unless the person has actually been booked into the Adult Detention Facility. Do not use CDCR money rules unless the person is in state custody, and do not use BOP money rules unless the person is in BOP custody.
| Where the Person Is | Mail or Money Rule | Wrong System to Avoid |
|---|---|---|
| County jail booking | Mariposa jail mail and account rules | Federal holding assumptions |
| BOP custody | BOP facility instructions | County jail kiosk or mycarepack |
| CDCR custody | CDCR send-money process | BOP or county rules |
| ICE custody | ICE facility-specific instructions | County jail or BOP rules |
| Unknown federal hold | Attorney, court, or federal agency guidance | Guessing an address |
Yosemite Federal Court Path
Yosemite and Mariposa federal matters may route through federal district court or federal prosecution channels depending on the offense, location, and custody stage. The research file points to the U.S. Attorney's Office for the Eastern District of California as the federal prosecution context for Yosemite/Mariposa cases. The Mariposa Superior Court portal is the county court path for state and local criminal cases, but it is not the federal court system.
For a Yosemite arrest, the arresting agency and jurisdiction fields matter. If the county booking PDF shows Yosemite National Park as the arrest agency or Yosemite as the jurisdiction, that tells the reader why the case may be different from an ordinary Sheriff's Office arrest. The formal charges may appear later in a court system, and the booking entry alone does not prove conviction, final charge status, or long-term custody location.
- Federal Hold
- Short-term custody tied to a federal agency, court, or transport decision.
- BOP Custody
- Federal Bureau of Prisons custody, usually after designation or sentence.
- USMS Transit
- Federal pretrial or transport custody that may not appear in BOP search right away.
- County Booking
- Local jail processing that can make the Mariposa Daily Booking Report relevant.
Yosemite vs Mariposa Jail
The main mistake in Yosemite custody searches is assuming that every Yosemite arrest is visible in the Mariposa County jail report. The report helps when the person is actually booked into the Adult Detention Facility. It does not cover every federal hold, every federal court status, BOP custody before or after transfer, ICE custody, or citations and releases that do not become county jail bookings.
| Question | Use | Why |
|---|---|---|
| Recent local booking? | Daily Booking Report and jail phone | Only if booked into county jail |
| Federal sentenced custody? | BOP inmate locator | BOP controls federal prison records |
| Federal pretrial custody? | Court, counsel, or federal channels | BOP may not list pretrial holds |
| State prison custody? | CDCR CIRIS | State custody is separate from Yosemite federal custody |
| Immigration detention? | ICE ODLS | No Mariposa ICE center was located |
Yosemite Federal Mugshot Limits
No public mugshot roster for the Yosemite federal holding facility was located. Federal agencies generally do not maintain a public mugshot roster comparable to some county jail sites. If a Yosemite/NPS arrest is booked into Mariposa County jail, the county booking report may show booking data such as charges, bond, arrest agency, and jurisdiction, but the inspected Mariposa booking PDF did not show a mugshot.
California's booking-photo rules also affect local publication when a state or local agency is involved. Penal Code 13665 restricts law-enforcement social-media sharing of booking photos in many nonviolent arrest contexts, and Civil Code 1798.91.1 restricts commercial pay-to-remove mugshot practices. Those rules should not be turned into a promise that a Yosemite federal booking photo is public online.
Note: Treat Yosemite custody as federal unless a verified county booking shows the person is held in Mariposa County jail.
