Secretary of Interior Ken Salazar will make his first visit to Yosemite National Park on Saturday.
He will be joined by National Park Service Director Jon Jarvis, who began his tenure as director this month.
The event will begin at 9:30 a.m. Saturday, with ranger-led hikes in Cook's Meadow, and an 11:30 reception at the old superintendent's house. Their tour will include views of recently-completed renovation projects, the park service said. Also attending will be Ranger Shelton Johnson, who was featured in Ken Burns' recent documentary "The National Parks: America's Best Idea." Johnson will present his award-winning Buffalo Soldier program.
