Yellowstone officials published plans to reopen parts of the historic national park to the public Wednesday after last week’s severe floods caused the evacuation of more than 10,000 people. Visitors will be permitted to enter the park’s south loop area at 8 a.m., but flood damage is expected to keep the north loop closed for a “substantial length of time,” the National Park Service said in a statement.

National Park Service officials are executing an interim visitor access plan, called the Alternating License Plate System, to welcome people back to parts of the south loop. Visitors can access Old Faithful, West Thumb, and other areas, but some areas of the south loop, such as the Norris and Lewis Lake campgrounds, stay barricaded.

Park officials announced exceptions to the system, including entrance regardless of license plate number for commercial tours and visitors with evidence of overnight reservations at hotels, campgrounds, or in the backcountry, according to the National Park Service. The license plate system is expected to offset the high demand for people wanting to access the park while ensuring the south look loop doesn't get overwhelmed with visitors.

Increasingly severe wildfires are occurring, including one last year that destroyed bridges, cabins, and other infrastructure in Lassen Volcanic National Park in Northern California.

Created in 1872 as the United States was rebounding from the Civil War, Yellowstone was the first of the national parks that came to be referred to as America’s best idea. Now, the home to gushing geysers, thundering waterfalls, and some of the country’s most plentiful and diverse wildlife is facing its biggest challenge in decades. Flooding has already done comprehensive damage in other parks and is a danger to virtually all the more than 400 national parks, a report by The Rocky Mountain Climate Organization found in 2009.
