Tennessee River Valley Glacier Activity???
Is it so far fetched? I doubt if you find anyone hanging a science degree or career on this hypothesis.
I became interested in the valley during numerous trips with the Army to the Chattanooga and Chickamauga Battlefields during what the Army calls "Staff Rides." Basically, the staff of officers or an Army historian details the battle and the rest of the staff walks the terrain of the battle.
My duty one day was to do the details of the last day of the Chickamauga Campaign a top the area known as the Fishhook of Missionary Ridge. As I walked the terrain, the features were very unusual.
There was a sharp face to the south and a sloping line to the north. I found a saddle in the middle. To the east side where the battle monuments stand is a rise of sediment.
As I walked the terrain westward back to the Confederate lines, the area turned into a sediment field cut up by numerous valleys. To the far west of the remainder of Missionary Ridge is a creek valley that runs along where Calvary officers would unload their horses for the staff ride from train boxcars. At this point, the ridge begins to break up and Pigeon Mountain takes over.
Further south along the valley between Pigeon Mountain and Lookout Mountain, there are large sediment deposits backed up against the mountains sloping back north. Some believe in millions of years of erosion. I believe some five to seven glacier periods and numerous melting and deluges did a lot of carving against these limestone and sandstone mountains. It could be a debris field pushed up against the north wall of the southern part of the Lookout Mountain Ridge.
How were the caves, now, tourists attractions, halfway up Lookout Mountain on the northeast face carved out? I found similar smaller holes in the cliffs of the Badlands, South Dakota.
Was Missionary Ridge part of Pigeon Mountain?
Was Sand Mountain, Lookout Mountain, and Walden Ridge all one at one time? Were they cut by millions of years of erosion or glacier deluge that broke the land between them and maybe others along the Tennessee River Valley?
In closing for the time being was Sequatchee Valley west of Walden Ridge a reverse glacier area. That pulls Grassy Cove to the north in of the Sequatchee Valley. It has unique features.
If one where to purchase the battlefield maps try to find Tullahoma, Chickamauga and Chattanooga Campaigns, by Col. WM.E. Merrill, Chief of Engineers, U.S. Army, 1874. It is a white and black map showing great detail of the Tennessee Valley. I bought several copies at the battlefield museums.
If one looks up the valley northeast of Chattanooga, one will see what looks like a railroad yard of ridges. Are these worn down mountains or could they be glacier deposits from the numerous mountain valleys up the Tennessee River from a melting glacier?
Was the Kentucky and Tennessee mountains saturated with smaller glaciers at one time feeding a massive glacier extending down into Georgia?
Did the deluge from this possible glacier or repeats of this glacier carve up the valley and break through Lookout Mountain and Walden Ridge cutting the rest of the Tennessee River Valley?
