Information about these landslides was provided by Mike Loso &#8211; he can be contacted at the following email address:-\u00a0michael_loso@nps.gov . I noted that he had kindly sent to me a video of the fourth of these events, shot from the air by Luke Wassink, a National Park Service Ranger.\u00a0 Luke and Mike have given permission for me to make this video available via Youtube, so I have uploaded it this morning.\u00a0 The video, which is remarkable, should be accessible <a href=\"https:\/\/www.youtube.com\/watch?v=Xh23H3QApk8\">here<\/a>, and I have embedded it below:<\/p>\n<p><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/Xh23H3QApk8\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>.<\/p>\n<p>I very much appreciate the help and support of Michael and Luke in making this available.\u00a0 The video is remarkable, not least because of the incredible power of the flow.\u00a0 But note that this event was tiny compared with the two largest events.\u00a0 Compare the deposit in this image with the trim lines left by the earlier flows in the image below, taken from the video:<\/p>\n<div id=\"attachment_21029\" style=\"width: 574px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-21029\" class=\"size-full wp-image-21029\" src=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2017\/01\/17_01-Mount-Sulzer-1.jpg\" alt=\"Mount Sulzer avalanches\" width=\"564\" height=\"349\" srcset=\"https:\/\/blogs.agu.org\/landslideblog\/files\/2017\/01\/17_01-Mount-Sulzer-1.jpg 564w, https:\/\/blogs.agu.org\/landslideblog\/files\/2017\/01\/17_01-Mount-Sulzer-1-300x186.jpg 300w\" sizes=\"auto, (max-width: 564px) 100vw, 564px\" \/><p id=\"caption-attachment-21029\" class=\"wp-caption-text\">Still from the video of one of the Mount Sulzer avalanches, by Luke Wassink.
