What is National Trail Mix Day?

The mix was created as a healthy snack that could be carried on hikes and is commemorated on National Trail Mix Day, which is observed annually on August 31.

It is believed by some that the trail mix was invented in 1968 by two California surfers who mixed peanuts and raisins together for an energy snack. However, in Jack Kerouac's book The Dharma Bums, the two main characters' description of the planned meals in preparation for their hiking trip is included.

Sometimes referred to as "Gorp" in the Trail mix, it is also known as "Gorp."
