Both pickers and gold nuggets have been uncovered in the crevices and cracks in the bedrock of creeks, which are connected to the tributaries from Sweetwater Lake. Do you know what other types of rocks can be found in creeks? Check out the most common rocks you can find in the creeks in the article below:.
Various fossils can be found in Indiana, dating back to the Devonian and Upper Mississippian periods. The southern parts of the state contain marine fossils, such as crinoids and bryozoans, plenty of which are found at Clarksville, at the Falls of the Ohio State Park. Brachiopods, corals, cephalopods, crinoids, bryozoans, conodonts, gastropods, trilobites, sponges, and shark teeth can be found in Jefferson County, at the limestone formations.
Sandstone, shale, and limestone deposits in Crawford County often host various fossils, where horn corals, blastoids, conularids, shark teeth, and pelecypods. The area near Fort Wayne, at the Maumee River, in northern Indiana, is filled with fossilized corals and petrified wood. The area road cuts and outcrops near Weisburg in Southern Indiana are home to various trilobite fossils. Still did not find the answer to your answers about rockhounding in Tennessee?

If you want to take rocks from creeks in Indiana, you need permission first, and you need a written license under IC and a notice from the department. However, you can ignore these rules if you take less than twenty-five cubic yards of creek rock within one calendar year from the parcel. The official state rock of Indiana is the Salem Limestone, since It is a sedimentary rock that dominates the terrain of Indiana. Limestone is made out of the shells and remains of tiny animals.
Thus it is primarily formed out of the mineral calcium. Indiana is among the few states in the U. This comes as no surprise, as gemstones are quite rare in Indiana.
For example, sapphire is found in only one location, Highland Creek, gold is sparse, and diamonds were uncovered in only two areas in the state.
Indiana has an unofficially designated state fossil, namely, the crinoid. Crinoid fossils are found in abundance in the southern parts of the state, in the Mississippian and Ordovician formations.
It is also encountered in the limestone formations located in Jefferson and Crawford counties. The Monroe Reservoir is one of the best known locations to find geodes in the state. When searching for geodes, look along riverbeds, construction sites or other areas that have been eroded away. In some areas geodes can be found along roadways. When searching along roads, make sure your vehicle is parked out of the way so it doesn't disturb traffic.
Geodes can also be found anywhere bedrock is exposed in the southern portion of the state. You just have to pick them up. The neighboring counties are also good spots to hunt. You want to look for roads that were blasted out of cliffsides. You can tell by the large cliff walls on either side of the road. Parts of those natural walls crumble apart over time, and geodes literally just fall out of them.
Indiana used to be covered by shallow seawater millions of years ago, and the entirety of the state is basically a dried-up sea bed. From my own personal experience, this is also a good way to find small chips of gemstones and other cool rocks. As the walls erode, those precious chips end up all over the side of the road, and they can be just as fun to find as geodes are.
They may not be worth anything, but they do look nice in a collection. When you do this, keep in mind that most of these natural walls are located on highways. Most of the walls have several yards of space between them and the road, but you still need to be careful.
There are a number of quarries throughout the southeastern corner of Indiana, and all of them are known for having large concentrations of geodes. You are permitted to pan the rivers of Hoosier National Forest with basic equipment - no commercial equipment, please. Keep in mind also that panning is not permitted in the Charles C. Deam Wilderness Area. Make sure to be respectful of the land. Let's make sure it remains unturned for generations to come.
