The 5 of you all go investigate as a group, since you are all tied together, and naturally that means traveling together. Which is far better then splitting off, any further then ten feet apart and you would be lost forever in the snow and the rocks. In any case, it still takes some solid effort to climb the debris to the spot and get a nice up to your face inspection.<br/><br/>Turns out the black spot isn't a spot at all, it is a hole. Bleakness and dark dark depths creep down and out from the hole punch through the wall, which it is. The natural rock was blown away at the edge to show worked and fitted masonry, each stone being a good 5 by 5. Nobody can see into the hole and what lays beyond.<br/><br/>While the party discusses possible dangers verses freezing to death, another bolt hits the ground where you were when you crested the ridge. Making a rather nice hole in the ground before the thunder ripples down the edge of the slope.
