Reiter Trails??

So my friend and I went up to Reiter today and had a ball. We ran the wall trail and the powerline trail. Before we headed home we wanted to run the isable trail. My question is, what is the name of the trail at the hairpin turn of the lake isabel trail called. It goes left of the main trail and winds its way down. We followed it a ways and turned around cause we did not know where it went. So, what was this trail called.

Also where is and what is the "Trail of Doom"

Lastly, how do you get up to the old mine shafts, is there a trail?
