This is the Freeze Out hill Southeast of Emmett, Idaho. If you go to Google Earth and punch in Emmett, Idaho and then click on "fly to" it will take you close to this site. The date on this ariel photo is June 23, 2007 which is Saturday. This satellite pass was in the morning between about 7 or so and probably 9.
