The Grand Hogback: Living Life on the Edge
The Grand Hogback is a 90 mile-long ridge of resistant, inclined rock layers of the Mesaverde Formation. It is one of the longest and most continuous hogbacks in North America. Can you outline it on this map?
We live life on the edge. It's a common phrase we use to describe our lives in the Roaring Fork Valley. The rivers, creeks, and mountains create the perfect terrain for extreme skiers, mountain bikers and kayakers "living on the edge."
What many people don't realize is that we truly do live on "the edge" in the geological sense. Our Roaring Fork Valley is nestled near the boundary of two geologic provinces.
Look at the map above. To the west of the Grand Hogback is the smoother, gentler topography of the Colorado Plateau. It's characterized by mostly horizontal sedimentary layers eroded into plateaus, mesas and buttes.
To the east of the Grand Hogback are the southern Rocky Mountains, produced by "extreme" geologic activity beginning 70 million years ago and ending 40 million years ago.
The Grand Hogback's central ridgeline is crowned by a series of serrated peaks ranging in elevation from 7,710 feet to 9,196 feet.
Colorado Mountain College is located in 11 mountain towns and has more than 80 degree programs to choose from.
