Five-Years Ago (03-November-2007) — Colorado

Autumn Road Trip in Colorado: Great Sand Dune National Park.

I drove from Boulder to southwestern Colorado to visit Alamosa National Wildlife Refuge. It was late in the season and very dry, so not many birds remained. I then traveled to Great Sand Dunes National Park. The sky was clear and blue. I took some panorama images of the sand dunes and the dry Medano creek bed. Most of the other folks visiting the park that day were there to climb and slide down the large sand dunes. I need to revisit both locations in the spring to see the migrating birds at the wildlife refuge, and  to see Medano creek with water flowing.

My interests include the natural world, wildlife, landscapes, sky, and seascapes, travel, and astrophotography. I look for unique ways of viewing the world and presenting my images. I have traveled to over 55 countries in six continents, often on Semester at Sea voyages. While at home in New Jersey, I spend time on home renovation and expansion of a wildflower garden/meadow.
