Northern Indiana Rockhounding Sites
Northern Indiana rockhounding locations are relatively sparse, but that doesn’t mean there aren’t plenty of places to search. The finds in this area are mostly going to be quartz-family minerals like agate, jasper, and petrified wood, but some locations may contain specimens of calcite, marcasite, pyrite, and even some small geodes. The best place to rockhound in northern Indiana is Fort Wayne, particularly in the gravels of the Maumee River and any recently tilled fields which may contain fr...
Central Indiana Rockhounding Sites
Central Indiana is the best part of the state for rockhounding, both for the number of prospective locations and the variety of specimens that may be found. Many quarries and road cuts in the area are known to contain interesting mineral varieties including fluorescent calcite, fluorite, dolomite, and celestite, and some of the local creeks and streams can be panned for gold. Perhaps even more interesting are the geodes which can be found in several locations including Beanblossom and Trevlac.
Southern Indiana Rockhounding Sites
Southern Indiana is an interesting area for rockhounding. There are many cave formations open to the public with are definitely worth checking out even though collecting isn’t allowed. Quarries in the region have long produced specimens of carbonate minerals like calcite, dolomite, and celestite. Any rockhound looking to do some collecting in southern Indiana will want to search for geodes in Lawrence County and the towns of Bedford and Heltonville.
Geodes are some of the most popular rocks sought by rockhounds all over the world, and Indiana is no exception. In fact, Indiana is a surprisingly good state for geode collecting thanks to the sedimentary rocks which cover the entirety of the state. These geodes form in cavities in the rocks when mineral-laden water precipitates through the voids a...
There is nothing quite like uncovering a quartz crystal with a perfect termination or finding a beautiful agate that has been waiting in a river bank for you to come along and take it home. Gemstones are some of the most enjoyable specimens that rockhounds can find, but it’s not always easy to know where to look. Due to Indiana’s complete lack of a...
Amethyst’s distinct purple color and hexagonal crystal habit make it one of the most recognizable gemstones in the world, and it’s no wonder rockhounds seek it out with such enthusiasm. It isn’t easily found in Indiana but you aren’t without hope if you’re looking to collect some for yourself. The best place to find amethyst in Indiana is in Willia...
One of the most common questions rockhounds have is whether or not they are allowed to collect at a certain location. It is the responsibility of each rockhound to obtain permission from a landowner to search and/or collect on a piece of property. The ownership and status of land can and does change frequently, making it impossible to document accu...
