There seems to be nothing topographical, geological, or geographical of note here besides the rock formations closing the Hallway in. Located in Western Manoa Lai, between co-ordinates E-4 and E-5, the Entryway Slope is known as the Sloping Hallway in the European release of Endless Ocean. It is unknown what the "entryway" part of this area's North American name is referring to, though perhaps the fact that the Slope leads to an almost room-like rock structure, albeit without a ceiling, could be what earned it that moniker.
