I am not a canologist but this one I found in the Mojave looks "kinda old". I'm tempted to soak it in rust remover and then take a wire brush to it.
I don't know. What do people do with old steel cans?
There are many abandoned mining sites where for quite a large area the scrub has collected cans and other containers that were thrown by the winds. I can't imagine that rust is great for the flora and fauna.
