Have you seen these, perhaps already found a cache in one? It is a MNDOT cylinder style delineator, X4-13! Normally found on the side of a road, often attached to stop signs. Guess what – there used to be a road here, but it was closed due to erosion by the creek. Now it is a short hiking/biking trail. You can park nearby and a short walk will get you to the 3 caches along the trail.
