The following list is a comparison of elevation absolutes in the United States. Data include interval measures of highest and lowest elevation for all fifty states and Washington, D.C.. Which state 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.
