Thirteen bison fresh from Wind Cave National Park will soon be released in Tallgrass Prairie National Preserve. Destined to become one of the preserve's main attractions, the charismatic animals restore an important element of biodiversity and historical character to a national park that was established to protect one of America’s last remaining large tracts of tallgrass prairie.

The U.S. Coast Guard is seeking National Park Service approval to install one or two search-and-rescue communication towers in Glacier Bay National Park and Preserve.
