Frost Gate Mission Cartography Question

With aspirations of acquiring the Grandmaster Cartography title for Tyria, I went about mapping out, and completing the Frost Gate Mission(and bonus) with my one week old necromancer "The Purity Of Pain".

I cleared out the south-east section after using the lever once.

Then I cleared out the north-west section after using the lever a second time.

My question is this: have I missed anything?

I ask this question for 2 reasons:

1) There are still some stone summit that remain, along the path that Rurik takes.

2) I have seen a map of this mission that has been fully uncovered, and there seems to be an area(or areas) that can be mapped in the extreme south and west parts.

Is there a way to get on the path that Rurik takes?

Thank you for any help you can provide on this matter.

There's a thread in the Tyrian explorers forum talking about getting the 100% Title. LOTS of good info there. A quick tip, tho - If you can still get into the ascalon & Yaks bend arenas, get in them and do at least one PvP battle to clear the out!

To Answer your question, no you can't get down to Rurik's path.
