Bottle dump

[gforce1972]

Been metal detecting a 30 acre site in York, PA that has houses built in 1700s, 1800s and 1901. The bottle dump is just huge. It is in a ravine and it is just bottles on top of bottles. These are off the top. I know nothing about bottles. Any help?

Hopefully you can find the older sections of the property.
These bottles are from the 1940's to 1960's era.
Good luck and happy digging.
