Death Valley is a deep trough between two mountain ranges. It is something over 100 miles long and averages 10 miles wide. Within less than 100 miles of Mt. Whitney, the highest peak in the United States proper, it sinks its lowest depression to 276 feet below sea level. This is official measurement; there may be lower spots in the valley still awaiting the surveyors telescopic eye.
