Mozo Shenno is one of the many Shrines located throughout Zelda: Breath of the Wild. It's connected to the The Bird in the Mountains quest, which you can pick up in Rito Village.
Where to find Mozo Shenno and The Bird in the Mountains solution
In Rito Village, speak to Molli - the young pink Rito that's perched on the edge one level down from where you fast travel into - to hear a story about her grandfather stopping at a big tree and looked northwest.
She'll point out the very tree - it's pretty much the highest you can see looking north, north-east. Use your telescope to mark it on your map.
Head there - take level two cold protection and expect a climb. Once there, you have to fly over to the north west from this cliff top.
We ourselves couldn't see the 'white bird' formation, but as you glide, you'll soon see the Shrine glowing underneath a cliff just after you pass a set of rocks closer by.

Glide straight into this cave to get the Shrine.
Alternatively, you could just head straight to the Biron Snowshelf where the Shrine is buried, but following the quest and going from the tree allows you to see it from a greater distance, and makes things a little easier.
Once inside, it's one of the game's many Test of Strength challenges - specifically against the hardest kind of Guardian Scout. Complete it and you'll receive a Diamond.
