Not sure the correct terminology for this question, but if you know the answer it should be obvious what I am asking about.
In the North, the snow area where you fight the thunderhawk near a vantage point. If you go past it and continue up the mountain you come to an area with an intense orange light shinning out of a hole in the mountain and a very deep drop near it.. To the left is some climbing areas, but I can't seem to progress much past them. I get to the spot about even with the hanging gear, but I see no further way to climb or do anything else. I just end up climbing down a couple ledges and using the grapple.
Am I missing something? If this has a purpose later, but I am not to it yet, let me know that and I'll figure it out. If not and you can offer a hint or three, please do.
