OK. So I was rolling down 67 from Butler to Mt City. The trails were just past Butler on my right side. If I am following your topography, then as I travel toward Mt City on 67- Iron Mt is to my left, Doe Mt is to my right. Stone Mt is on the other side of 167 (which splits Doe and Stone..)..
App trail follows Iron Mt ridge top.... I think
The trails that I saw were kinda fresh. A few ATV track trails and a few bike only trails leaving out from Hwy 67. Possibly they connect to the Doe Mt trail system by locals who dont wanna pay the fee?? idk
What would you attempt to do in life if you knew that you could not fail?
