Sewemup

Sewemup WSA

The Sewemup WSA is unique for its outstanding naturalness. Historically an obscure and little-traveled region, the Sewemup Mesa derives its name from the cattle rustling days of the McCarty Gang. It is said that rustlers burnt off and "sewed up" the cattle's rightful brands in exchange for their own - hence the name, "Sew 'em up." It is obvious now why a band of rustlers would have chosen Sewemup and the vicinity for a hideout, as this WSA is a place with very little human traces.

Impressive sandstone cliffs, which almost entirely surround the mesa top, make access difficult; therefore, this WSA is one of the most ecologically pristine areas in Colorado. The mesa is surrounded by sheer, 500 to 700-foot cliffs on three sides. The southern edge of the mesa has a broken, rocky slope, rather than a solid cliff face. From the mesa top, scenic vistas of Sinbad Valley and the La Sal Mountains are available. The outside edges of the valley contain small, hogback-like formations that dip away from the center of the valley, thus revealing the general shape of the salt dome before its collapse.

Wingate Sandstone's 1,000-foot-high cliffs encircle more than 3/4 of Sewemup Mesa. Domes of pink-banded Entrada Sandstone also dot the top of the mesa.
