The Mount Williamson herd is one of the original native Sierra bighorn herds, but has remained small in numbers since it was first studied. In approximately 30 years of study, this herd has held steady at under 20 animals total in population. The SNBSRP began collaring animals in this herd in 2008. In the spring of 2017 we had a total of four animals collared there. This is an area where we've documented immigration from another herd. In 2009, at least 1 bighorn ewe travelled here from Mount Baxter and took up residence in the George Creek area. Other ewes have traveled between these herd units, but it is not clear if they immigrated or were just visiting.
