The night returned and the dwarves continued to work on the stone across hey had accomplished munch in the short time. The rangers woke and began to eat some of the rations. The dwarves had iron poles and had begun to push the unusable stone to the valley below. One of the cave trolls foolishly tried to catch one of the larger pieces only to be crushed. To your amazement he did not die. The others lifted the bolder off him and in a few moments the crushed troll was standing.

The sound of the falling rocks with the warming air causes a large section of snow to give way and fall away. You can see a clear cut path that anyone one could walk across and reach the other side of this mountain then it would be a simple part of climbing down to the valley below and far from the trolls. The altitude you could see the land stretching before you. The forest at the foot of the mountains would be helpful to hide your approach but there would also be danger there.
