About mid-afternoon last Sunday, Ludwig's old elevation record of 8640 feet, which had stood since 2004, fell to a col in Yellowstone National Park, Dunraven Pass, 8859 feet above sea level. (The sign says 8859 ft and the park-issued map agrees; the USGS says 8878.02 feet. I'm going with the figure on the sign.) This is also the highest paved road in the park.
