Legend is there  that a  sage used to take  bath in both rivers Yamuna and Ganga daily. In his last days, keeping in  view  his  incapability  to  cross   the  mountains and  glaciers daily, the benevolent mother Ganges appeared  at   Yamunotri   itself  which   still  flows down a rocky hill and worshiped as Ganges. The small Yamunotri temple was built by Maharaja Pratap Shah of Tehri.    Like  Ganges  at  Gangotri,   here  too  the  Yamuna    is     worshiped   as   a   river  as   well  as  a  Goddess.
