From Alamosa take Highway 160 East about 10 miles to Highway 150. Take Highway 150 to the park entrance.
This shot was taken in August while exploring the dunes interior. Isolating these few sunflowers in the frame gave me the look I was after.
This photo was taken in Great Sand Dunes National Park in Alamosa County, Colorado. The park contains North America's highest dunes with some reaching heights of 700 feet.
