Eighteen visitors were evacuated overnight after powerful thunderstorms triggered multiple mudslides that buried a mountain road inside Colorado’s Curecanti National Recreation Area, temporarily trapping more than 20 people in a remote section of the park.
According to the National Park Service, intense rainfall on the evening of July 16th sent debris rushing down steep drainages above East Portal Road, burying long stretches of pavement beneath as much as six feet of mud, rocks, and boulders. The slides also overwhelmed the East Portal Campground and much of the nearby picnic area, forcing an immediate closure of the area.
The incident left 21 visitors stranded at the bottom of the six mile access road that connects travelers with Crystal Dam, the Gunnison Tunnel, and popular recreation areas inside Curecanti National Recreation Area and Black Canyon of the Gunnison National Park.
Overnight Rescue Clears Most Stranded Visitors
Emergency responders reached the scene within about 45 minutes after the storm struck. National Park Service law enforcement officers joined facility management crews from both the National Park Service and the Bureau of Reclamation to secure the area and begin clearing the roadway with heavy equipment.
By midnight, crews had successfully evacuated 18 stranded visitors without any reported injuries.
Three people remained overnight. One motorcyclist and two visitors dealing with vehicle problems stayed in place until daylight because the road remained heavily saturated after the storm. Those three individuals were safely evacuated by 9am on July 17th once conditions had improved enough for travel.
The successful evacuation came despite difficult conditions created by unstable slopes, heavy debris, and continuing concerns about additional slides.
Campground and Road Remain Closed
The National Park Service says East Portal Road, the campground, and the picnic area will remain closed while crews assess the damage and begin repairs. They have not released an estimate for reopening or the total cost of the damage. The closure applies to all traffic including vehicles, pedestrians, and bicyclists.
East Portal Road is managed by the Bureau of Reclamation and serves as the only access route to several popular recreation sites. The road features grades as steep as 16 percent, making recovery efforts more challenging after major storm events.
Burn Scar Raises Ongoing Landslide Risk
The area affected by the mudslides passes through terrain burned during the 2025 South Rim Fire. Burn scars often create dangerous conditions during heavy rain because vegetation that normally stabilizes hillsides has been lost. Without that protective cover, water can quickly saturate loose soil and send mud, rocks, and fallen trees downhill with little warning.
The National Park Service is urging visitors to use extreme caution whenever storms move through recently burned landscapes. Even relatively brief periods of intense rainfall can produce flash flooding, debris flows, and landslides capable of blocking roads or trapping visitors.
While no injuries were reported in this incident, the rescue highlights the hazards that can develop rapidly in mountainous terrain during the summer monsoon season. Travelers planning trips to western Colorado should monitor weather forecasts closely and be prepared for sudden road closures, especially in areas impacted by recent wildfires.
Park officials say assessments and cleanup efforts are ongoing, and visitors should expect the East Portal area to remain inaccessible until crews determine it is safe to reopen.
