[pct-l] hiker trail vs. pack trail on Goat Rocks

[CClark]

In the Goat Rocks Wilderness, how does the hiker trail over Old Snowy compare to the pack trail through Packwood Glacier? I am looking for the least snowbound or slick route. I don’t mind more miles or elevation gain if I can avoid a snow field. 
 We’re planning to hike this area about August 8, but could postpone to Aug 15 if going one week later might make a significant difference in the amount of snow remaining. Any thoughts on that, from someone who knows the area? 
  
Should I bring microspikes? 


 Thanks,
Carolyn
