In "National Park Roads: A Legacy In The American Landscape," Dr. Timothy Davis details the history of a relationship as fragile and monumental as Glacier National Park’s Going-to-the-Sun Road – full of ups and downs, twists and turns, challenges and beauty. It is a story that many of us take for granted; after all, a park’s road serves as a de facto tour guide for most visitors, and that’s due to intricate planning and inventive engineering by park leaders for over 100 years.

Tranquil as it seemed as I ambled across the rolling meadow that gained the moniker “Bloody Angle” for one of the deadliest battles of the Civil War, the images that crept into my mind were vivid.

Because it runs almost 2,500 miles across the United States, there's wisdom in traveling U.S. Route 66 in bites.

If your focus is the Land of Enchantment, a good guide for such a trip is New Mexico Kicks On Route 66.

While the bay’s waters are known as the foremost source of sockeye salmon, the mountains surrounding the bay are also sources of great mineral wealth, and therein lies a conflict. Carl Johnson’s gorgeous, and human, photography does a fine job of showcasing a way of life that may be threatened by the Pebble Creek mine that long has been proposed to dig into the landscape.
