paragraph_text: Which state or territory is ``highest ''and`` lowest'' is determined by the definition of ``high ''and`` low''. For instance, Alaska could be regarded as the highest state because Denali, at 20,310 feet (6,190.5 m), is the highest point in the United States. However, Colorado, with the highest mean elevation of any state as well as the highest low point, could also be considered a candidate for ``highest state ''. Determining which state is`` lowest'' is equally problematic. California contains the Badwater Basin in Death Valley, at 279 feet (85 m) below sea level, the lowest point in the United States; while Florida has the lowest high point, and Delaware has the lowest mean elevation. Florida is also the flattest state, with the smallest difference between its highest and lowest points.
