The Arizona Geological Survey have created a rather nice virtual field trip and very useful virtual field trip about the Marcus landslide in Arizona. It is available here:<\/p>\n

http:\/\/www.azgs.az.gov\/MarcusLandslide_2008.shtml<\/a><\/p>\n

The slide is a 500,000 year old rock slide that has has a length of about 2 km from scarp crown to deposit toe (see Google Earth image below) and a deposit volume of about 5.25 million cubic metres. The elevation difference is about 500 m.<\/p>\n

Two minor criticisms from me, though:<\/p>\n

    \n
  1. The site does not give the lat\/long of its location, which makes looking at it on Google Earth rather more difficult than it ought to be. The location of the crown is: 33\u00b040’47.27″N, 111\u00b048’1.31″W. The deposit extends almost due east from this point;<\/li>\n
  2. The site states that “Poised for collapse, a heavy rain, a bolt of lightning, or an earthquake could have spontaneously triggered”. It is highly unlikely that lightning would trigger failure.<\/li>\n<\/ol>\n

    Finally, there is a paper in Geomorphology describing the landslide in more detail, including its dynamics, failure and age. It is available for downloading as a pdf<\/a> here. There reference is:<\/p>\n
