1) Easy to get. Talk to the stupid Owl at the beginning of the game in the north-east of the Kokiri Forest.
2) Sea Dog's Dojo - When you enter that multicolored maze, from the start, go
West three times, then bomb the north wall. You need the L2 Arrows for these to use on the flames blocking your way in that room.
3) Deku Tree F-2:
Spikes facing West - From the beginning of F-2 in the middle of the map, go north, north, west, north.
4) Lost Hills mountain cave. A little hard to describe. You know the little girl west of Pulcheria Village that serves as an entrance to Crystalia? Three screens north of her there is a bombable cave entrance that needs a Super Bomb. Go in there, and go three screens east, one screen south.
5) Capitol Port: Climb the vines in the upper-right of the area, go all the way to the top, and travel all the way west. Not hard to find at all. Except,
you need the L2 Candle from the Excavation to get this.
6) Go to Blester. Two screens east of the area you start in, (When it's snowing) there's a cave. As soon as you enter the cave, hop into the pit you see right before you. Go a screen north, and it's in that chest. Easy as pie. And falling on spikes voluntarily.
7) Twilight Lands - Find the entrance to the Cave of Mirrors. The Container is a screen to the east of it. You'll have to work your way up and around it to get there though.

Excavation B-3: From the start of the floor, go into the east wing, and work your way up to the screen northeast of the starting screen. Bomb the north wall. It's in the chest next to the archaeologist.
