Stop Stealing Signs in Hyalite Canyon This ordeal has been a big issue for the Custer Gallatin National Forest and we can understand why. KBZK is reporting that several signs totaling thousands of dollars have been stolen from the Hyalite Canyon area and it's become a pretty big issue for the Custer Gallatin National Forest Service. By the way, we are talking about small signs either. According to the Custer Gallatin National Forest Service, they are missing signs big and small. Most prominently, the Lick Creek trailhead sign has been missing for a bit and signs marking multiple trail junctions are gone as well.
