Platform Cairn

There seem to be four basic types of stone piles in this area. This video documents one particular type. It is a round platform cairn. They are usually between 15 and 30 feet in diameter. They are often found on hillsides facing the sun. In the video I say that they are stacked better on top. What I should have said was that the up hill side of the cairn is usually well stacked and taller than the downhill side of the cairn. Maybe gravity causes this effect or maybe they were built this way to maximize sun exposure.
