Yes. Between Gray and Monticello, 50 meters east of highway 11. Locals call it "The Rock".
Boulders that have been carried by a glacier have a couple names, but most commonly they are referred to as glacial boulders or erratics. If you're interested in learning more about glacial boulders, the Iowa Department of Natural Resources has a pretty good article about them; as Iowa and most of the American Midwest were covered by glaciers during the last Ice Age, glacial boulders are fairly common there. http://www.igsb.uiowa.edu/browse/boulders/boulders.htm
Glacial grooves are caused by the ice picking up boulders and scraping them across the bedrock.
Glacial erratics aren't exactly formed. They were deposited by glaciers that were moving in that area at one time. improved= Glacial erratics are exactly formed. Because a glacier is so heavy, the glacier can pluck large rocks as the glacier moves. When the rock is too heavy for the glacier to hold, or the glacier is retreating, it then deposits the rock in a place where it wouldn't usually be found. This is what an erratic is. A large piece of rock in an unusual surrounding. i hope this helps :)
It could be two things, either plucking, a form of glacial erosion where weak rock is moved or erratics, which is a form of glacial deposition in which rocks, even car size, are transported by glacial ice into a region with different bedrock.
horns, cirques, Ushaped valleys, and glacial lakes. Glacial erratics if your doing it for
The debris of boulders eroded and carried down by glaciers will eventually form moraines (mounds) where the front of the glacier melts and retreats, leaving the debris behind. Moraines can be high and wide enough to form a dam, behind which glacial melt water is trapped and lakes are formed.
Erratic blocks or "erratics" for short.
They are called glacial erratics if they are different from the local surrounding rocks.

Erratics were discovered by first humans in Ireland.

Rocks that have been transported from their place of formation are known as erratics (these commonly occur in areas where glaciation has occurred and so are known as glacial erratics).

You are possibly thinking of the Moeraki Boulders, on the coast about 50km north of Dunedin. These are spherical concretions up to 1.5m diameter, naturally growing in clays derived from volcanic ash. Still quietly emerging as the coast erodes. In the mountains, giant boulders are frequently found, and some are huge. The biv rock in the Upper Arawhata is several tens of metres lin each dimension. In the Troyte, a small valley off the Karangarua, (Westland) the boulders may even be seen in satellite photos! These are all ex-glacial erratics.
