การทำฐานรากเสาเข็ม: A Day at the Ranch (Not)

April 9, 2010. Windy, passing snow squalls, and cold temperatures. But a good day for a drive to Glacier National Park (no images today, check the April 10th, video), but a good enough day for checking out the Hungry Horse Dam (near Hungry Horse, Montana). Video and images by Daniel. Featuring Mr. Al Barnicle, and the views around the Hungry Horse Dam. Camera: Canon SD990IS The following is from the US Department of Interior, Bureau of Reclamation information at: www.usbr.gov Hungry Horse Dam Overview Hungry Horse Dam is 564-feet-high and has a variable thickness concrete arch structure with a crest length of 2115 ft.
