My buddy Dwight McCarter and I hiked with Bob Lochbaum and Ken Wise on an unmapped trail near Collins Gap to find this relic. The trail comes to an abrupt halt and nearby is this steel tooth. We believe it was from a piece of road making equipment. The area where this trail is does make sense to build a road. A trail could have been planned this way and stopped. However this piece remains a mystery. Its about a foot long and is very heavy. I think it attaches to a backhoe or shovel machine and it came off or was discarded. In fact on modern road construction equipment these teeth are replaced rather than having to buy a whole new bucket or scoop.
