The Celebration of Art Exhibition and Sale is open to the public at Kolb Studio through Jan. 20, 2025. Proving once again that the Grand Canyon is the perfect place for artists to come and fill their canvases with the inspirational colors, shapes and shadows of this world wonder, Grand Canyon Conservancy (GCC), the nonprofit to the Grand Canyon National Park Service, hosted its 16th Celebration of Art fundraiser (COA) in September.
