The largest flat top mountain just 69 Statute Miles (60 Nautical Miles) north of Ouray. This western slope of Colorado is filled with “wonders” like this… take a view at The Grand Mesa from above, a bird’s eye view. This large mountain between Grand Junction and Ouray is visible from miles away. The obvious flat top seems to run for miles and miles. It is unusual compared to the mountains around Ouray which are definitely not flat top.
