Logging camp bottles

[Section10]

Here are 2 bottles I found back in the '90s when I was working for a surveying company doing contract work for the USFS. They were lying on the surface at an old logging camp site that I'm sure had never been touched since it was abandoned. They have no seams and the tall one has a lot of horizontal rings up to the neck and the neck is very striated with vertical ridges. The smaller one is smoother. Both are unmarked. I put 4 or 5 in my pack and since we were only passing through, I had little chance to explore other than see some outlines on the ground where buildings had stood. It is a very difficult place to get to and I never considered going back, but I think it would be a really neat place to poke around in. Could anyone say how old they may be?
thanks,
Jim

The one on the right appears to be a turn mold bottle...
