How long does it take for a snake skin to lose all visibility of color & pattern after it is shed? I am just curious. I was working on cleaning out an overgrown corner of my back yard today & decided to get an old plastic sandbox leaned against the shed & take it to the front yard. My wife wanted me to clean it up so we can use it for my son in the front yard. We can't leave it in the back because my old Australian Shepard mix insists on peeing on it every time he is near it. So I got it & the lid for it which was laying on the ground next to it. I was careful as I always am when picking something like this up to pull the far side of whatever it is towards me so if something is underneath I can let the lid/object fall back on top of what is underneath if necessary. So anyway I picked it up & drug it to the front yard. Threw down both parts & grabbed the hose. That is when I saw the shed skin stuck on the underside of the lid. I brought the kids out to see it as I have been trying to get them to think about how they pick things up in the yard. My oldest girl noticed you could still see the pattern on the skin. It obviously came from a copperhead. I killed one in the back about a month or so ago so I know they are around. I should have took a pic but I wasn't thinking about it & scrubbed it off with an old broom. First time I have seen a skin with a recognizable pattern on it.
