Obviously the person is included in this photo solely to give you a sense of scale, not because it was totally awesome to creep out and touch the giant 9-foot-long icicles.
When we were starting the hike, there was a family (British?) coming back down. Their daughter, who was probably about 10 or 12, was carrying a javelin-length icicle in her mitten. Now that's parenting I approve of.
