Other/historical names associated with this locality:
Etango
A uranium claim (mine) ca. 4 km SE of Goanikontes and ca. 27 km E of Swakopmund, at a distance of ca. 40 km from the Rössing Uranium Mine.
Famous for excellent boltwoodite specimens (often with erroneous locality labeled as "Rössing" - https://www.mindat.org/loc-3085.html - or "Langer Heinrich" - https://www.mindat.org/loc-194264.html ).
Apparently now (after exploration restarted in 2010) called Etango (
