This was from the point we stopped and turned back after 6-hour hike. Do you see a blue dot at the top of second mountain? That is the lookout my boss intended to take us to. I just found in the website just now about this trail "The hike to the lookout is very difficult and strenuous. The last 0.5 mile of the trail requires mountain climbing equipment expertise. A short, steep section of the Three Fingers Glacier must be traversed, followed by a rocky scramble and ascent of steep ladders to the lookout on the south peak of Three Fingers Mountain. As there is considerable exposure, those using the cabin and ladder must determine for themselves if the climb to the lookout is safe. Maintenance of the lookout is performed by Everett Mountaineers."

Lesson learned: Study the trail before you go hiking!
