In OoT, in Gerudo Valley, you can use Silver Gauntlets to lift a gray(silver?) boulder on the entrance edge of the valley (around where the wooden sign is) for a secret grotto. There's a little pond with rupees in it with Inside the Deku Tree music playing. I name this Quietedge Splash, since it uses peaceful quiet music, it's on the edge of the valley, and once you get out, your only options are to go back in for the grotto pool or make a splash at the bottom of the canyon.
