You are looking for a small plastic lock top box. Grayville Falls is a beautiful spot in Hebron. Great for hiking, photography, and picnicking. Parking is just at the end of Reidy Hill Road. Cache is hidden just off what looks like s small fisherman's footpath. The path becomes overgrown in the summer - more of a challenge but still very findable. Stay on the parking lot side of the river to find the cache, there is a bridge upstream if you want to explore this beautiful place after you find it.
