I don't know if dangers is the right word. I would use the word risks.
I did not want to discourage you, I just wanted you to know the risks involved in this adventure. Maybe you should give some thought to going this winter with the idea of going as far as your skills and clothing will take you. We started our winter trips to this area staying the night at Lone Pine Campground, then progressively working our way up the mountain over the next several years. Now, we usually base camp at Lone Pine Lake.
