Breath of the Wild
The Ulri Mountain is a grassy area located northeast of the Akkala Tower and northeast of the South Akkala Stable. It shares a lot of the same characteristics as the Kanalet Ridge, just to its southwest. It is on a higher elevation, looking over the Torin Wetland to the south and the Shadow Pass to the west.
In the grassy areas, Link will be able to find some Hyrule Herbs, Hightail Lizards, Restless Crickets, and Warm Darners. Link will encounter some Maraudo Wolves and at nighttime, some enemy Stalmoblins.
At the east side of the mountain, there are a trio of apple trees and if Link matches them, he'll get a Korok Seed. A second Korok can be found at the west side of the area, located underneath a pile of leaves.

Make the tree with too many apples match the others.
Cut away the leaves and pick up the rock.
