We did not dig very much. Just scoped out the surface. The surface is about 1946. Found some coke and Whale Brand soda and more. As a newbie How do you find spots to dig deeper?
Dig a few small holes where your surface finds are. that will tell you pretty quick if it is just a scattering of stuff on the surface or a trash pit. If you find yourself digging in a trash pit (fingers crossed), a potato rake is a good tool to dig through everything with little risk of breaking a bottle. There is no sure fire way of knowing without digging. Even the best diggers dig plenty of unproductive holes.
Will try and do some test holes. A large tree had fallen a while ago and there is bottles in the whole...Weird. Not a lot of cans though I did see one rusty cone top.
