For anyone trying to get this shrine first go to Battleclast shrine in GC. Head north approx 70 meters hugging the mountain. here you will see a torch from there follow the many torches up the mountain and it will lead you directly to Mokash Springs Shrine.
There is a very nice mountain hike built by the devs, start from 'Battlecast Shrine', go north halfway to Svikin's Stand and follow the torches up the rocks, ledges and ridges. Scenic journey
how to get there?
This night hike was a blast, very fun, thanks for posting Ryan!
