Most avid hikers know Half Dome. In fact, as the signature landmark for Yosemite National Park, its image is recognized worldwide. It’s even on the 2005 U.S. quarter. From late-May to early-October, visitors can attempt this extremely strenuous 16-mile round-trip day hike. The main challenge is the nearly one mile vertical climb from the valley. Then there’s the final 425 feet, aided by a 45-degree inclined cable banister.

Iconic images from the National Park Service’s first century are captured forever in three limited-edition coins from the U.S. Mint, and proceeds raised from selling the coins will help shape the next 100 years through projects and programs.

A soaring new 3D IMAX film premiered recently, showcasing the wonders of national parks from Katmai in Alaska to Everglades in Florida. Narrated by none less than Academy Award® -winner Robert Redford, the film was created by the National Park Service and Brand USA in honor of the Park Service’s 100th anniversary and is airing here and in 60 countries around the globe. Intended to showcase the best of our nation, the film falls woefully short as critics have pointed out, because it features only athletic, young white Americans recreating in pretty places.

Memorabilia collectors have an extra incentive to visit Yosemite National Park this year: new branding of the hotel once known as The Ahwahnee, a tent village now being called Half Dome, not Curry, and Wawona Hotel now known as Big Trees Lodge.
