Pretty cool.
The rock balancing sculptures are native to Inuit peoples of North America (Eskimos for you tards), and are used as a way of communicating with each other. ie: 'Kilroy was here' or 'Nanook passed by here yesterday at about chinese dentist time (tooth hurty)'
I see this stuff all around the mountains, and came across a gathering place where there were hundreds of 'Inucsuks' noting that a entire tribe had gathered there.
