Two photographers were in the right place at the right time. While Denali National Park is often smothered with clouds and drenched with rain in August, a climatological anomaly placed a narrow ridge of dry warm air across the state of Alaska, bringing clear, mist-free air to the mountains. On a flight-seeing tour of a lifetime, Mary Linda Miller and Carmelo Monti captured in an hour sunlit views that might otherwise require numerous trips to see. From the Talkeetna River to Mount McKinley, with two cameras facing in opposite directions, their images reveal vast expanses of boreal forest, marshes, streams and lakes; glaciers of every size and shape, from origins to terminus; and worn-smooth foothills rising to the crescendo of the tallest snowcapped peaks in North America. "An Hour Over Denali" contains a collection of 75 time-stamped aerial photographs taken on August 11, 2011 during a flight-seeing tour over Denali National Park and Denali State Park; an introduction that describes the process in greater detail; a map that defines the flight-seeing route; and descriptions of the photos that tie them to their locations.
