Knowing that the nearest hospital was 100 miles away, and that it has just 25 beds and four ventilators, made it relatively easy for Big Bend National Park Superintendent Bob Krumenaker to decide to close his park to the public Thursday after one of his employees was diagnosed with Covid-19.

While Big Bend National Park closed Thursday due to a confirmed case of Covid-19 within the park's community, other parks are moving carefully in granting visitors access, and at least one concessionaire is requiring customers to wear facemasks, a Fourth of July celebration at Mount Rushmore National Memorial will not require face masks or social distancing.

The interpretive wizards at Yellowstone National Park have released a new and improved app to make your visit to the park more efficient than ever before. The Yellowstone app not only helps you explore Yellowstone, but lets you log your memories within the app.

Just as the Blackfeet Nation is taking steps to guard its members against Covid-19 by closing access to the eastern half of Glacier National Park, the Havasupai Tribe is banning outside entry to its reservation, and Grand Canyon boaters have been asked to respect that.
