Near Grenville, New Mexico. A singular, irregularly shaped promontory in the high plains ranch country of west Union County. In the 1800's, Santa Fe Trail travelers called this Round Mound. In 1887, it was renamed at the request of US Senator Stephen Dorsey to honor his son, Clayton. In photograph Santa Fe Trail marker is in foreground. Round Mound is seen from US Highway 64/87 looking WSW.

Part of the Raton/Clayton Volcanic Field (East). Major SFT landmark and pilot knob. Mentioned in several SFT journals. Cimarron Route of SFT skirted N base. SFT travelers often climbed to summit for spectacular view of high plains. SFT crosses US Highway 64/87 5 Miles SE of Grenville, and NM 453, 4.2 miles SSW of Grenville (Both are part of Scenic Byway).
