Reverse Mountain

A mountain at one of the points where the four Blues meet. This place is unique in that rivers from the Blues flow up the mountain, meet at the top, and then flow down into the Grand Line. Many pirates entering the Grand Line die before they can even get up to the top of the mountain, because the hostile water currents and storms force them to crash into the mountain walls. At the bottom of the mountain lies the Twin Capes, a place to purchase a log pose from a group of strong merchantmen.
