Named by the USGS (1901). The reference here is probably for wild Nelson Bighorn [or Mountain] Sheep (Ovis canadensis) that still range freely in this area. This summit overlooks their natural habitat. Nearby Sheep Creek was named at the same time.
Name first appears on USGS indio Special Map (1904).
Name officially accepted by USBGN (1963).
Peak was on the original 1946 HPS Peak List.
