Hunters Guide

So I'm going through the hunters guide with my partner finally and we're trying to complete them. Though we can't seem to find Bonethorn, which is something I need to complete my guide. Could anyone give a screenshot of a map location and description where some is or let me know if there's an Xbox glitch preventing them from showing? We've been looking for three to four hours and have looked it up with multiple sources and still can't find it. Any help would be appreciated!
