Based on Snotel data from Potato Hill, this year is similar to last year and you shouldn't have any problems getting to the Killen Creek TH towards the end of June. Last year I accessed the Killen Creek TH on June 8th from the north side with only a one mile road walk. The north side of 2329 melts out faster than the south side. Use the following FR's to access Killen Creek from the north; 23, 21, 56, 5603, 2329.
