💀 The forbidden trail 💀

I hiked a short, but permanently closed trail today. I did it because it is still on the maps and GPS... so up I went. I found out at the top of the trail there were 🛑 signs... but there were no signs at the bottom where I started. I guess my first clue should've been that there were no signs at all. I spotted what looked like a possible trailhead that was partially obscured by debris, but further ahead I saw a tell-talke trail marker on a tree. These markers should have been removed when the trail was closed. Other clues are in the pics!
