The Grand Mesa National Forest is described as the largest flat top mountain in the world! it was the third forest reserve created in the United States. It is managed by the Forest Service along with the Uncompahgre and Gunnison National Forests, all three located on the western slope of the Colorado Rockies. The Mesa sits at close to 11,000 feet above sea level and about 6,000 feet above surrounding communities like Grand Junction. I was told that the fall color on the Grand Mesa was spectacular a week ago by a lady I met while doing laundry at the KOA camp in Silt. Nothing better than a personal recommendation based on experience.
