Nape piercing
Somewhat less common are surface anchors, commonly made from surgical implant-grade titanium. A surface anchor has two parts: a base or foot which is inserted under the dermis during the piercing process and which incorporates a stem exposed to the surface, and a decorative disc or ball of jewelry which typically appears flush with the surface of the skin. Surface anchor nape piercings are most commonly found placed symmetrically on either side of the spine at the nape.
Anchor Dam
The concrete thin-arch dam was completed in 1960 by the United States Bureau of Reclamation as a water storage project. The -high dam structure impounds the water of the South Fork of Owl Creek, with the spillway as designed as a central overflow "notch".
