PERFECT PLACES TO HANG OUT IN THE WOODS

An Inukshuk is a stone landmark used as a milestone by the Inuit of the Canadian Arctic. Though varying in shape and size, most are comprised of rocks placed and balanced on top of one another, and symbolize safety, hope and friendship on the barren tundra of the Canadian North.

In Japanese, the pile of rocks is called "obos." 

"If an object or expression can bring about, within us, a sense of serene melancholy and a spiritual longing, then that object could be said to be wabi-sabi." (Andrew Juniper, from his book "Wabi Sabi: The Japanese Art of Impermanence")
