• Incident overview:
“The Inn Fire started on Thursday May 22, 2025 at approximately 3:36 p.m. on the west side of Highway 395, just south of Mono City. Erratic winds caused the fire to grow quickly and spot across the east side of Highway 395. A full suppression response was ordered by fire management, including firefighting aircraft. Highway 395 was immediately closed in both directions for safety and for the threat and impacts to power lines. Evacuation orders were issued for Mono City, then Lundy Canyon after, with evacuation order downgraded to a warning at 9 p.m. on May 24. The fire was called 100% contained at 6:00 p.m. on June 4.

• Projected incident activity:
“Minimal smoldering and hot spots may continually put up visible smokes as firefighters work to control this fire in a peat-soil component which continues to hold heat near containment lines.”
• Planned actions on this wildfire:
“Patrol for any smoldering remaining hot spots, continue to assess effectiveness of completed suppression efforts.”
• Weather concerns:
“NWS Reno: https://forecast.weather.gov/product.php? Site=REV&issuedby=REV&product=AFD&format=CI&version=1&glossary=1.”
• Significant events:
“Minimal, smoldering”
• Other remarks:
“Although the fire is 100% contained as of June 4, 2025, a season-ending precipitation event is needed to call this fire fully out. This may not happen for several months due to the peat-heavy soil component that tends to hold pockets of heat for extended of periods of time.”

Fire containment
What does 100% containment mean?
Note that full containment doesn’t mean the fire is completely out. In this case, it means that the whole perimeter of the wildfire has been surrounded by a control line and it is now stopped from spreading. A fully contained wildfire may continue to burn within the containment perimeter but is not likely to spread.
However, there’s a significant difference between containing and controlling a wildfire. After the fire is fully contained, the next step is to control it. Controlling a fire means ensuring that the fire can’t spread or cross the containment line.
Containment is part of a larger plan for managing a wildfire. It is normally expressed as a percentage and it refers to how much of the fire perimeter has been surrounded/enclosed by a control line that firefighters create. The containment percentage indicates a certain level of control, but it doesn’t always correlate to safety level. Also, it’s important to note that containment doesn’t mean a fire is out.
How is containment measured?
The incident’s central command constantly receives progress reports from firefighters on the ground. As the fireline is constructed, inspected or reinforced, mappers record those details to adjust the containment percentage. The percentage tells the public how much of the fire perimeter is believed to not go beyond the control lines.
