Ship Rock is a famous "volcanic neck" just south of Farmington, NM. It is not visible from the Four Corners monument but is visible from Mesa Verde, Colorado. US 666 is now US 491, a sop to the superstitious and Biblically ignorant, who are unaware that in Revelation, 666 is the number of a man, not a highway.
The prominent ridge in the southeast corner of the map is not an igneous feature at all, but a hogback, a ridge of steeply upturned, resistant sedimentary rocks.
Best access is via a paved tribal road that intersects US 666/491 about 10 km south of Farmington. Myriad dirt roads lead to the base of the rock. It's difficult to get lost since heading south will take you to the tribal road and heading east will take you to 491/666.
