We are reaching the end of the season when some water supplies are inadequate.
It is always best to carry extra water then to count on some springs for your trip.
Here is a map of were the water is supposed to be near Mine Shaft Camp from Hikin Jims Blog:
If you are doing the SB 9 Peaks then your other chances for water along the divide would be at:
High Meadow Springs, Trail Fork Springs and Limber Pine Springs.
Remember to be safe and careful with the weather this time of year.
