So, I found a turn of the century dump and I pulled out a straight sided coke where the wall of the dump drops a little below the level of the creek bed. In other words, I pulled it essentially out of the dirt underneath the water. The dump is right on the water and is even below the creek. Any tips on how to dig in these kinds of dumps? Most often the water just refills the hole with mud. It's also a shame, since the freezing and thawing likely caused a lot of these bottles to break. As for the part that is on dry land, I'm not sure if water seeping in and flooding the dig hole would be a problem. Anyone know? Thanks in advance!
