We had the same problem. We didn't go back to the trail to relocate though we just moved over to the next spur. I suspected it was plotted wrong but was open to me attacking incorrectly. As we crossed the reentrant we saw the trail. I realized I misinterpreted the first intersection as the trail going down, which I am guessing by you making the same mistake there was a trail going down as I thought. Just also one going up, which I wasn't looking for.
yes the trail junctions were off, i think the trail we came in on was not the one on the map? we figured it was the next spur over but didn't like the looks of trying to climb those boulders so went around. and then confirmed by the trail in the reentrant as we went in.
There were many routes through the boulders
