Grand Canyon Kolb Studio Renovation 2013-14 (32) - Flickr - Grand Canyon NPS

Kolb Studio — clings to the edge of the South Rim of the Grand Canyon, in Grand Canyon Village, Grand Canyon National Park, Arizona.

It was the home and photographic studio of Grand Canyon pioneers, Emery and Ellsworth Kolb, and was begun in 1904.
Today, this historic studio is open year-round. It contains an exhibit hall, bookstore, and information center operated by the Grand Canyon Association.
