Because, no matter what we do, we can't actually figure out who they are or how they ended up there.
Theories range from a freak hailstorm taking out Raj-jat yatra pilgrims or a massive army to Nanda Devi punishing a king and his army for his wife giving birth to their child in this sacred land.
Whatever truths does history hold, the fact remains that they are still there today, and we think that they've been rather observant of all of us trekkers passing through- after all, they've got to do something to pass the time, don't they?
They’ve got a bone to pick (very intentional pun) with the way people summit to the lake and turn right back around to return down to base camp. According to them, you're missing the best part of the trek, and honestly, we couldn't agree more.
While by no means is the actual Roop Kund unimpressive, it pales in comparison to the stunning sights of the rest of the trek, which is gifted with endless jaw-dropping scenes, the best of which is situated quietly just above the Roop Kund summit.
