My Theories... Re: Sasquatch Stick Structures

What are they?  Why are they always seen in and around suspected Sasquatch/Bigfoot habitats?  I think they are some sort of road marker, like "this way to camp" for visiting clans.

If you gather reports from around the US and Canada we can summize that they are somewhat Nomadic.  What if various Clans of the Bigfoots have a mating season where they "join together" for mating and/or birthing purposes, like the Whales that all give birth in and around Maui during the Winter months.  They call that part of the island the Maternity Ward.

I remember reading a report of a man hiking in the woods when he came upon a cave.  He heard some faint noises that sounded like "crying babies" so he decided to investigate.  He followed the noises and was shocked to find a sort of "Nursery" of human/ape like creatures.

Here are some un-natural "stick formation" pictures gathered from around the web....
