I was wading in a creek today and imagined if a little rock was the size of a person. Then I thought about how something like that would even be possible. I came up with a few ideas but am still unsure.
How could a creek (like the one above) exist at a much larger scale in the in the real world?
The area in question does not need to be on Earth, it could be on a more volcanically active planet, lower gravity, stronger weather, etc.
And just to clarify, if you size down a river, it does not look the same as a creek, so please don't tell me rivers exist, I do realize that.
