Audubon Nature Calendar 2009

The plunging sandstone cliffs of Zion National Park. Oregon's misty and ethereal Proxy Falls. The oranges, purples, and blues of sunset over California's Mono Lake. It's a year of North America's most dazzling natural treasures, photographed up-close and in vibrant full color. Each of the images—dramatic, pristine, and grand in scale—is an impressive tribute to the beauty and power of the wilderness. [via]
