Who painted this?
You're looking at Aaron Draper Shattuck's painting of Madison Boulder in Conway, New Hampshire. Shattuck is part of the second generation of the Hudson River School, a group of artists who drew and painted the landscape around the Hudson River valley and upwards into New England.
Shattuck worked for most of his life in New England and never studied abroad. He tried to be as faithful as he could to the details of the scenery he depicted. Madison Boulder was something of a landmark in Conway! It was more than 30 feet in diameter and people went to the forest near Madison just to see it (and paint it, if they were artists!).
