Golf great Greg Norman — known as the Shark — has listed his breathtaking $40 million Colorado ranch, we’re told.

The 11,900-acre Seven Lakes Ranch straddles the trout-filled White River outside Meeker, according to broker Hall and Hall, and the 13,900-square-foot log house has eight guest suites, a “soaring double-sided moss rock fireplace, rustic bar and commanding views” of the valley below.

There’s also “an authentic saloon/dance hall” on the property.
