A carpeted green waterway and fleeting cloud cover frames That Tree on April 8, 2012.
In early 2012 photographer Mark Hirsch, of Platteville, Wis., was still recovering from a near-fatal accident when he took a picture
of an ancient Bur Oak tree in a nearby cornfield. Hirsch used a new iPhone rather than his standard camera equipment.
Inspired, Hirsch began a year-long project to capture a picture a day of the oak, finding solace, and heretofore hidden beauty, in his towering, monumental subject.
The results not only became a viral sensation; as he told CBS
' "Sunday Morning
," the project gave him "healing and inspiration that I needed more than I had realized."
