Ill-prepared hikers thought they could summit Mt. Whitney in two to three days with only Clif bars as fuel.

Redditor Choniepaster was a back country trail worker in Kings Canyon/Sequoia National Park in California and reported, " [I] ran into a group of about 4 people who were trying to hike to Mt. Whitney and back in two-three days (around 70-80 miles round trip from where they started) and they only brought cliff bars and a space blanket. They ended up getting chased down by the nearby ranger and escorted out of the back country.
