The looser deposits you describe are more likely outwash or lacustrine deposits that were not glacially consolidated. Most of the big slope failures in recent years (Perkins Lane in Magnolia, Whidbey, Bainbridge, Oso) are the result of slope failure in outwash or lacustrine deposits and not glacial till.Anonymoushttps://www.blogger.com/profile/00001237701152529744noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-32837489932052340252014-03-29T16:07:22.689-07:002014-03-29T16:07:22.689-07:00Yeah, when I've looked at buying I've alwa...Yeah, when I've looked at buying I've always gotten the geological maps and paid attention to the landslide locations -- realizing that most landslides move extremely slowly, most of the time.<br /><br />The list of ignored warnings (the "Cassandra file") is always worth a look. <br /><br />Worth thinking about: the projection that precipitation events may become more intense, and more local, as climate changes. Look up the paleo work and you'll find talus slopes and landslides all over the world that haven't been active during the most recent period of unusually stable climate -- but will be again.<br /><br />http://scholar.google.com/scholar?q=paleo+landslide+talus+precipitation<br /><br />Of course, people fly hang gliders and ride bulls, so it's hardly surprising we build houses in landslide areas.Hank Robertshttps://www.blogger.com/profile/07521410755553979665noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-81613692994670824522014-03-29T12:03:54.005-07:002014-03-29T12:03:54.005-07:00This is very good.

Till's high clay content makes it somewhat porous, but not permeable; it can be soft and weak when saturated and concrete-like when dry. Till typically makes up a fairly small portion of glacial sediments, which taken as a whole are typically a pretty weak stack of sediments. buried_foresthttps://www.blogger.com/profile/05486696810044589104noreply@blogger.comtag:blogger.com,1999:blog-7478606652950905956.post-1018221211650902082014-03-29T11:23:23.956-07:002014-03-29T11:23:23.956-07:00Are there any geologist blogs or other resources l...Are there any geologist blogs or other resources listing other areas in Washington that are at similar risk? Evidently there were geotechnical warnings about Oso in 1999 and 2005. What other ignored warnings have people been making, and about where?
