earth gift shrine (gba)

The FFI Guide may have not been updated because these places were featured until GBA.

Look for tree triangles, groups of three, follow whatever direction they point out, eventually you'll find an oasis and the next floor, if you're familiar with FFIV Advance's Lunar Ruins, you'll find out upon multiple runs (which you have to do 4 runs on this place to fight all bosses) the floors randomize and eventually you'll end up in the desert again, just follow the tree triangles again.
