A Petrified Tree Stump

On the lawn of the Pettigrew House & Museum in Sioux Falls, South Dakota is a large petrified tree stump. It stands roughly between two and three feet tall. It is hollow, but I was unable to get clear photos of the bottom of the hollow from the right angles high enough to model it. It was acquired by Senator Pettigrew for his burgeoning private collection which was eventually turned into a private museum.

I created this model in Agisoft Photoscan Pro.

I took 52 photos around the tree stump
