There are a lot of things most people don't know about hiking.
For example, did you know...
Trail Magic—Occurs when strangers, so-called "Train Angels," leave food and other supplies along the trail for other hikers to find.
Hiker Trash—Long-distance hikers affectionately use the term to describe themselves, referring to their rugged and carefree lifestyle on the trail.
Hiking Speed—An average hiker does around 2-3 miles (about 3-5 km) an hour, but ultra-light hikers can cover up to 30-40 miles (ca. 48-64 km) daily.
For experienced hikers, this stuff is common knowledge.
But some of these might surprise those who have not spent much time on the trails.
For example, here's the weirdest thing most people don't know about hiking:
Singing Rocks
"Singing" rocks, sometimes called "whistling" rocks, produce musical tones when struck or, more often, when the wind blows through them in a certain way. This natural phenomenon is typically caused by the rocks' unique composition and structure, which can create resonant frequencies.
Crazy.
So, watch for nature's hidden melodies on your next hike.
