Thought some may be interested in seeing this rock we have locally. It has a bowl on the top of it and a groove running off the side. It is in a very isolated area where two creeks come together.

Interesting rock. Do you have any pictures of the bowl and groove?Bruce
In life there are losers and finders. Which one are you? -
I keep trying to upload but it says the file size is too large. Hopefully I'll figure out a way to make it smaller shortlyComment

That is definitely interesting !Comment

Essex - that reminds me of something you might see in South America where the indians did sacrifices. Strange but really interesting. ..ChuckPickett/Fentress County, Tn - Any day on this side of the grass is a good day. -Chuck-Comment

That is called a " Glacial erratic". At some point in time, maybe 40,000 plus years ago, glaciers moved into that area. When they did, they carried huge boulders of rocks with them. There would have been a flowing water source near that rock that washed over it. At the time, there were smaller pebbles on top that kept swirling around by the water action, slowly eroding out a depression. It's hard to visualize and maybe understand, and maybe Rodger or someone else can offer a more definitive explanation, but that's basically what that boulder is. A glacial erratic left behind when the glaciers receded.Comment

Hi Paul, good explanation as to what and how the bowl formation developed except not for how the boulder got to its present location. Supposedly glaciers never got as far south as the southern Appalachian Mountains during any of the Pleistocene glaciations. Essex doesn't say how far away from or how high above the present two streams is this rock. Not knowing those facts makes it hard to make a guess. This could be a remnant of periods when stream levels were much higher, etc. If we knew more about the exact area and its local geology would be helpful.

This site here has a good visual aid to what Paul is trying to describe. http://www.geo.mtu.edu/KeweenawGeohe.../Potholes.html

Thanks Hoss, I needed some visual explanation for what I was trying to say, and you took the time to find it! That's why your an administrator, you take the time to help others. Thanks, I appreciate that. PaulComment

Beat me to it. Paul is quite correct. Look also at the base of that erratic and how eroded it is. That rock has been sitting almost submerged in fast-flowing water for a loooong time. That's the kind or erosion which sometimes ultimately leaves erratic boulders sitting perched on top of a tiny pedestal, like someone has balanced them there.I keep six honest serving-men (they taught me all I knew); Their names are What and Why and When and How and Where and Who.Comment

I also think Paul is correct except as to how it got there. Probably not by glaciers as I said in my direct comment to Paul. Setting in water for a "loooong time" yes, but not likely moved to where it is now by a glacier.Comment

HAH! I finally beat Rodger! I'm going to have a cold one and celebrate!! That's all I ever wanted to do. I need to get a life! Have a good holiday, Rodger! And Hoss! And everyone else!!!Comment

It depends on what geologic map you look at. Some maps show the Laurentide Ice Sheet of 90,000 - 20,000 years ago, ending at the northern Kentucky border. Other maps show it advanced as far south as the northern borders of Ala. and Ga. During the geologic Pennsylvania Period ( 200 mya ) , glaciers advanced north from the south pole, and covered some areas of Georgia. Georgia has under gone some very unusual events from glaciers, volcanism, the Appalachian Mountain foldings, and at one time, ( Mississippian period-320 mya ) ,almost the entire state was covered by a shallow sea. It's an amazing subject to study, how natural events shaped this entire country.Comment

The rock is probably 20 yards from where the two creeks meet. I'd have to disagree with the speculation on how the bowl was carved into the top. It may be hard to tell from the picture but it has been carved by someone and a channel grooved from the bowl down the rock. Many indian artifacts have been found in this area and down the creek numerous Paleolithic artifacts. Never heard any theories that involved glaciers in this area but who knows.Comment

if Paul says it,then i would absolutely believe it
if Rodger says it and agrees,then you can bet your bottom dollar on it
two very intelligent guys right there that know their stuff
Rodger is the guy one this site,that the rest of go to for verification on such things
probably the smartest guy i have never met
ive learned more on this site from them two guys than i ever thought was possibleComment
