thanks I got it actually right after I posted this question. Now I just can't get my coordinates to be accepted and I know they are correct

So I just finished the water plant and I'm trying to find the next constellation. I've read a walkthrough and it says I have to find the necklace again. Problem is idk how to get back there. I've tried getting there from the quarry but I can't get over the wall again.
