You'd still need tunnels to get to Bart Island!
If someone can do a picture from the Dynamap with routes on and with coordinates, I'll give it a go....I'm on level 12 diamond hunting at my base anyway, may as well tunnel with a dual purpose
Bart, do you know if the sea around your island goes lower than say level 14? If so, how low at its lowest?
Also, how high and wide a tunnel di we need fir a rail car?
C'mon, let's do this as a community side project!
