How to protect and preserve archaeological sites
Record the site's location and boundaries.
The existence of an archaeological site should be noted on the deed to the property at the county recorder's office. The deed also provides the boundaries of the property itself, so you can determine if additional permissions will be required to excavate the site.
When you begin excavation plans, an archaeological preservation easement should be created. This is a deed limitation that allows archaeologists to continue plans to excavate and preserve the site even if you sell the land.
