I looked at the picture of Giant at the Bailey's website. Great picture. And that is really, really big! I invite others to make their own guess, but using landmarks in the photo, I think the highest jet is at least 220 ft. Using the people in the foreground as a metric is a clear underestimate, given that they are 100 ft. closer than the eruption. That gives a height around 170. Using the cone is a little too far and overestimates, but that gives a height of around 270 ft.... It looks as if there is significant wind, and that the eruption has been going on at least a little while. What were the first jets like??? Correct me if I'm wrong.
