Spectacle Rock

Spectacle Rock is a recurring location in The Legend of Zelda games, and first appeared in the first game of the series, The Legend of Zelda.

Characteristics
Spectacle Rock is a rock formation of two parallel rocks, that is always found on Death Mountain. They often have some kind of role in the progress of the game.

The Legend of Zelda
In The Legend of Zelda, Specatcle Rock was located to the northeast of Death Mountain. If the player bombed the left rock, the entrance to Level-, Ganon's lair, was revealed.

Zelda II: The Adventure of Link
In Zelda II, the player can use the Hammer on the eastern rock to reveal a magic container.

The Legend of Zelda: A Link to the Past
In A Link to the Past, Spectacle Rock only exists in the Light World, where it blocks the route to the Tower of Hera, making the player temporarily enter the Dark World to bypass it. Between the rocks is a cave route that leads down and out of Death Mountain.

The Legend of Zelda: Ocarina of Time
In Ocarina of Time, Spectacle Rock appears inside the Death Mountain's crater, in front of the entrance to the Fire Temple. Its appearance is more conic or heaped, and a Piece of Heart rests on top of one of the rocks. Volcanic smoke billows out of the tips of each rock, though there were no natural chimney stacks visible at the peaks. It is evident from its structure and that of the Fire Temple that the upper floors of the Fire Temple extend into the interior of these two mounds.

The Legend of Zelda: Twilight Princess
In Twilight Princess, Spectacle Rock are two huge rock formations near Death Mountain. The southeast one (southwest in the Wii version) houses the Goron race, while the northwest (northeast in the Wii version) one houses their Goron Mines.

The Legend of Zelda: Wind Waker
In The Wind Waker, an island known as Spectacle Isle can be found on the Great Sea. It is made up out of two hills, but is a long way from Dragon Roost Island, which is generally speculated to be Death Mountain.
