I just defeated The Bunker during the mission Where Angels Fear to Tread, and was taking in the view when I noticed one of those incandescent-bulb directional arrows off in the distance.
It is high atop a mountain and points down to a plateau beneath it, and just below that plateau is a lake, where if you watch long enough you'll see a thresher spawn.
So I'm wondering if that's an Easter Egg of some sort, or is it truly an area you can reach?
I'm playing on the PS3.

Your a viewing Terramorphous the Invincible (small spoiler). It's a mission (You. Will. Die. (Seriously)) that you will recieve way later in the game and the area is accessible only via thousand cuts.
