Our recording stopped and lost a good portion of our track. It also happened to be the steepest part of the track that got lost. The actual hike (we had a second device recording) was 6.79 miles with 1482 in ascent, 1456 in descent. Lots of history along this hike. A little steeper than most in the area, so you might want to be fit and/or carry a light pack with water & lunch.
