I knew once I saw the topic, which photo I would post. This is a piece of skunk cabbage in the spring. While it wasn't stinky when we say it - it had yet to grow the leaves, its a smell easily identified in our neck of the woods. Found primarily in wetlands and swampy areas, it's pretty easy to spot. It's smell isn't too bad unless you break off a leaf, and then it's pretty foul.
