Thankfully you won't find labled trails. SD is a sensitive area as far as closures and the wheeling folks up there have done a great job of keeping the trails out of the magazines. Contact DTC or Black Hill 4 Wheelers before you head up and I'm sure they would love to show you a great time! Here is a link on the RS forum from BHCC....lots of yak and reposts but a good sort of pictures.
