Help!

I've not been playing Bo for long but I enjoy it so far. I've completed 3 quests and now I seem to be stuck... If anyone can help guide me that would be great.

I've just unlocked my "dash" ability and I seem to be stuck in this green area of the map. The only way out appears to be back up a HUGE shaft area but I can't get to the top. Am I missing something simple?
