| Note: | I observed Steamboat from around 1840 to 2015
.
I spent an hour from 1840-1940 at Steerage logging runoff over middle rock and observing the trench. The trench is filling rapidly with gravel. Each wave of runoff, even small ones, are sending gravel into the trough. "Elvis" rock is undercut by several inches now. The runoff channel has been scarred and heavily altered since the winter with large patches missing and new large rocks and debris.
As for the minors themselves. What I saw seemed to be an improvement of the observations by Jeff L. There is some nice strong South and North action. With both throwing some vertical shots in occasionally during stronger concerted minors. There were several heavy concerted (but NOT vertical) minors that put water about halfway up Middle rock (2.5-3 on my runoff scale).
After I finished my hour of detailed observations. I headed up to the Lower Platform where I observed three consecutive strong concerted minors (2003, 2007, and 2010) that put a flood of water with visible rocks roughly the size of tennis balls down the channel. It looked like it would have covered middle rock. The first minor in that cluster started out with some vertical shots but did not sustain, and the two following were weaker and shorter, but still had decent volume. |
