Hello! This is why you follow the rules at our National Parks! This is a terrible tragedy that could have easily been avoided. I was young once, and I did plenty of reckless things. I understand, maybe the boy was just trying to check the temperature. Maybe he didn't believe the signs, or he thought it would be cool to do what no one else has done. His poor sister! To see that happen! To see her own brother boil to death. I can't imagine how gruesome that must have been. I just can't believe they couldn't get his body until the next day...and the next day it was gone! This is a huge lesson for anyone that is young and reckless!
