I was a bit confused by all the squiggly lines in the GPS app. And I was relying too much on the two other people to know the way and to use their GPSs. I think that now I would be more confident and more comfortable with the gpx, since I used it to navigate back down later in the day.
Another thing is if you go the wrong way too far it becomes quite hard to go back. That area is made up of rocks of various sizes, so instead of walking you are jumping from rock to rock. We were lucky there was trail nearby. The maps I saw at REI only show one trail going to the summit, they don't show all the variants.
