Cranmer Park is a city park in Denver, United States located in the Hilltop neighborhood off Colorado Boulevard between East 1st and East 3rd Avenue. It is notable for its large sundial. An inscription at the base describes the axis of the gnomon as elevated 39°43' in the direction of polar north. The stone is perpendicular to the gnomon at 50°17', which makes it parallel to the equator. The south side of the stone is similarly marked for wintertime observation.
