We visited Norris on July 9 while exiting the park. We were mainly heading for Vixen but spent some time on the Steamboat platforms. I would guesstimate 70% concerted function, some of it fairly strong. My understanding was concerted function was what you *wanted* to see, but I noticed that one of the new signs indicated that "consistent north function with strong overflow" was the "only known precursor" for an eruption. Realizing we don't have an abundance of data points here, is strong North function what you want really? I'd been led to believe strong concerted had the best positive correlation to an impending eruption. Help?
