Historic Hood River
This Alan Winans slide was also with the Camp Yallani views, but it’s from much later. It’s dated to March 27, 1996, which was one of the key flood dates for the Hood River. I recall a USGS scientist explaining to me this event laid the foundation for the November 2006 flood which created the river delta we see today. I might be misremembering the numbers, but I think he said this event brought 750,000 cubic yards of sediment, but the delta was still mostly submerged until another 750,000 yards were deposited in 2006. I believe both events were “glacial outbursts” where rain on top of snow and ice sent a pulse of water filled with sediment downs the river channel. Can someone verify the geology/hydrology?
