Hey Tyoshi, I am also planning on hiking up via the main trail next weekend. I called the ranger station last wednesday and I was told that there was a recent successful summit via the main trail. I was also told that melting snow was the best water source right now, but I believe that will probably change come the end of this week. No other details unfortunately so I hope someone else could give some insight.
Are you planning on camping just 1 night? I am trying to figure out the best course of action, as I attempted this last winter and had to turn around because of wind and snow conditions.
