If you want to compare before and after you can look at historic images on Google Earth. The location of the slump is at 48° 16' 57" N 121° 50' 50" W. There is an image from 2005 with one that you can compare with from 2006 after the first slump. It changed the course of the river by about 250 meters.Quantumleap42https://www.blogger.com/profile/16711817313734546305noreply@blogger.comtag:blogger.com,1999:blog-30940686.post-46804685620573600182014-03-29T22:43:07.243-07:002014-03-29T22:43:07.243-07:00I appreciated a couple that came out afterwards hi...I appreciated a couple that came out afterwards highlighting the warning given previously and also exposed irresponsible logging higher up which may also have changed the hydrology which may have had an impact.<br /><br />Here they are:<br /><br /><a href="http://seattletimes.com/html/localnews/2023218573_mudslidewarningsxml.html" rel="nofollow">The Seattle Times: "Risk of slide ‘unforeseen’?

We're not talking invasive species here, but what occurs naturally. The idea is that cutting and thinning water greedy trees will increase stream flow to down elevation reservoirs. But other reports are warning of the mud, rocks and other debris which will actually clog such waterways.<br /><br /><a href="http://timeless-environments.blogspot.se/2014/03/stupid-unscientific-things-said-about.html" rel="nofollow">"Stupid unscientific things said about Forests and Trees"</a><br /><br /><br />-Chaparral Earthhttps://www.blogger.com/profile/00618976919417073750noreply@blogger.com
