The Original Tunnel Trail Found!

Following the Jesusita Fire a curious discovery was made- another route off the main Tunnel Trail. It wasn't until recently that a side view of the trail was possible to see the extent of this "other" trail. As the two panoramas below clearly show, a second original "Tunnel Trail" runs on the south side of the mountain where the current Tunnel runs today. When was it last used, who built it, and why did they change the route? All good questions even the FS didn't know. Hit us up if you know the answers. Possible new trail????
