Deldrimor Bowl Mapping Issue

I am having trouble exposing the map in Deldrimor Bowl. You can see in the guide map, how far east the map is exposed compared to what I can scrape. How do I extend the exposed map further east like the guide? I've gone over that area a number of times perfectly slow and perpendicular but cannot seem to find the rest...

Iirc, there are a couple spots that enable 'end of the world' use

I.E. the map suddenly ends

Try running up a few mountain sides until you find it

You cannot expose every bit of the map. You have probably cleaerd all that you can in Deldrimor Bowl.
