I have been entertaining the idea of a glacial erratic for my newest module.

I'm thinking of something similar to this

and this rock caught me eye while looking at some gravel today.

I think I can make it work by cleaning it up and somehow and making it look more exposed to the elements.

Hi Dee, Maybe some dark moss color on the shaded areas?  For anyone interested in learning more about erratics  Nick Zentner has some interesting lectures on youtube. Look for Central Washinton University,geology,Nick Zentner.....DaveB

Deem, I would.........

........sink it into the base a little.  
 

Up here in northern NY we call these guys Glacial Moraines.  I have a giant one on my land up at our summer house in the Adirondacks. if I can find a picture of it, I’ll post it.  Great idea.  You are definitely an "out of the box" thinker.

They are not the same.  A morain is sediment deposited by glaciar usually in the form of a ridge.  A erratic is rock or boulder that has been carried a distance by glacial I and then left behind when the ice has melted and retreated.  I researched glacial while a geology consultant in upstate NY for a number of years.  

Now anyone want to model a drumlin?

Peter, Indeed, it needs to be

Peter,

Indeed, it needs to be sunk a bit. I have to cut through the layer of grout and into the foam to do so and will probably  do that this weekend.

Look forward to your pic.

DaveB, Thanks for the

DaveB,

Thanks for the link.

The locale I'm modelling is going through an unusual dry spell so I'm researching how this rock may look like. Maybe some dusting on it to depict the clayish dust of the area settling on it?

Jim,The closest thing I made

Jim,

The closest thing I made to a morain is this embankment. It's more like an eroded one that grass grew on.

Now I will have to look up to see what a drumlin is...

Glacial anomolies

In simple terms:

A drumlin is an eroded feature, formed under a glacier as it moves and encounters an immovable object. It is characterized by the streamlined  shape, with the  wide/high end pointing towards the source of the ice movement.

A moraine is formed in front of a glacier, made up of the gravel and ground stone collected by glacier as it moves, and left behind when the ice melts and the glacier retreats. The moraine often forms long, sinuous hills marking the limit of glacial advance. In some areas where glaciers repeatedly advanced and retreated, you can find multiple moraines.

An erratic is a large boulder, usually rounded in shape, that is carried within the glacier from it's original geological point of origin and left behind when the glacier melts. They usually have no relationship to the geoogical formations in which they are finally found, and may have traveled hundreds of miles with the glacier to their final resting place.

Other formations you might see are pinnacles, sandstone formations usually found today in the southwest, in areas where the glaciers split and did not erode existing landforms, "Garden of the Gods" in Colorado is one such formation, and there were some smaller ones in Moraine, Ohio (see where it got its name?) on Pinnacle Road, though they were unfortunately lost to development.

I dug a hole,

Deemiogos, nice looking

Deemiogos, nice looking moraine ridge!

We had Drumlins in upstate NY, IIRC, in the Rochester area.  

As an aside, I hold a bachelor's and a master of science in geology.  My masters thesis was in karst ground water flow but I did study glacial geomorphology quite a bit as well.  But these days IT pays the bills.

Well Jim, I will certainly

Well Jim, I will certainly have to consult you, if that is ok, when I work on my fourth module.

I'm honoured that you like my moraine ridge, as I did little research on it and just winged it with childhood memories of the locale I model.

On the next module of fifth module, I want to achieve a similar look to this.

Well, well, it looks like...........

..........the folks in the Adirondacks have it wrong!  Who knew?  It’s not quite the same as some of the regional terms I find so endearing.  In the Adirondacks a "summer home" is called a camp.  In the Rochester and Buffalo area (Jim Fitch), the same structure is called a cottage.  To many people a camp is a tent, fire pit and stinky outhouse!  A lot of out of state people are quite surprised when they arrive at my "camp"!

These are also called "camps".......!

I will be spending this next summer trying to teach everyone that our moraines are really erratics.  I really like the sound of moraine so muck better! LOL

Deem, looks so much more natural that way, much less erratic!  Damn, wrong again...........

California erratics

Hi to all, some erratics left there since the last glaciation in the California Fott Hills..

Peter,My ex has a camp up on

Peter,

My ex has a camp up on the east end of lake Ontario near Polanski and Sandy Creek.  It's right on the lake.

I always wondered if they used the term camp because to NY city folk, they were like camping.

 

Deem, best thing in scenery is to follow nature and copy it.  Looks like you are doing a great job.

Have you heard of the “Big Rock?”

And no, not Newfoundland. 
I grew up not far from this. The scale of the thing is immense.

Flood erratics

It's interesting that some erratics ended up far from the glacial ice, carried there by floods on broken off rafts of ice. Eventually the ice rafts melted and the rocks were left.....DaveB

Cotttage/Camp

"Camp" is extensively used in northern Ontario for any type of wilderness cabin.

No drumlins for me, but maybe we could do some eskers or kames.

Maybe we just call that rock a really big chunk of glacial till.

Then there's the odd landings

Like Tripod in NJ -  An erratic that is NOT set into its surroundings... if it were, it would be boring!

Nope - definitely called camps on Lake Ontario

Now you have. 

Me, having grown up on the west coast from age 7 -24, and got married at age 28, I never heard of cottages or cabins referred to as "camps" until my ex-wife and her family.  They all referred to them as camps.  To me it was a curious term at first.  There is a whole neighborhood of them just north of Sandy Pond up Route 3 on Montario Point.  That family was from Syracuse NY.
