Pack Life Support
Just how many days before your chunk of cheddar becomes a biohazard? It’s Claudia Pearson’s job to know. As NOLS Rocky Mountain Rations Manager, Pearson is in charge of supplying food for the program’s month-long expeditions. Here’s what she knows will go the distance—and what you’d better eat on day one. (Note: Pack life estimates are for typical summer alpine conditions with highs in the 70s; hotter weather or leaving food out in the sun can significantly speed spoilage.)

1 Day:Eggs, broken into
2 – 3 Days:Goat cheese
