Here is an idealized sketch of a marker pile site: the piles are almost evenly space and lie along lines which lead uphill to a high elevation horizon. At an actual site there may be dozens of the these lines of sight. Some other features which occur at marker pile sites are
- aperture piles
- lines which lead to a ledge with a quartz rock on the ledge
- prayer seats
Here is an example from Stow.
And here is a view uphill to the east at The Hill of 500 Cairns.
