Question

Search and Rescues at U.S. National Parks

(1) Annual attendance at the parks managed by the National Park Service has grown over the years. (2) In 2017 alone, more than four million people visited Washington State’s three national parks Mount Rainier National Park, North Cascades National Park, and Olympic National Park. (3) The parks are breathtakingly beautiful, but they harbor unsuspected hazards. (4) As annual park attendance continues to rise, so does the number of lost or injured hikers requiring search-and-rescue missions (SARs).
(5) The importance of SARs is clearly illustrated by a day in the life of the helitack crew based at Mt. Rainier National Park, in the state of Washington, as reported on the National Park Service Web site (NPS.gov). (6) On June 24, 2018, the helitack crew made three rescues. (7) These rescues provided critical aid to visitors at each of Washington’s three national parks.
(8) In the morning, the crew rescued a young hiker experiencing respiratory problems. (9) In the late afternoon, they brought an injured and disoriented 55-year-old hiker in to safety. (10) The first rescue was at North Cascades National Park the second was at Olympic National Park.
(11) The members of the helitack crew received its final call of the day shortly after making their second rescue. (12) They rerouted their return flight to help rescue several injured climbers on Mount Rainier at 9,500 feet above sea level.
(13) Thanks to the efforts of this helitack crew and the other brave men and women of the NPS, the National Parks are much safer places to visit.
