South Dakota Rockhounding Location Guide & Map

If you’re wanting to do some rockhounding in South Dakota you’ll be excited to learn that there are some truly amazing rocks and minerals to find here, and plenty of places in which to find them. Most of the best rockhounding sites are in and around the Black Hills, but the rest of the state is not without potential.

The highlight of South Dakota rockhounding is undoubtedly the highly prized and valuable ‘Fairfield agate’, a variety of agate noted for its vibrant colors and distinctive fortification banding. These agates are named after the town of Fairfield around which they are most commonly found, and they are very popular with lapidary artists and collectors.

While South Dakota is a great state for rockhounding in general, it helps to have a good idea of where to look and what you can find in each area. I have put this article together to give you a sense of they kinds of rocks and minerals you can find and where to start looking.

The best places to rockhound in South Dakota are in Custer County where Fairfield agates and rose quartz are both found in relative abundance. In general, the gravel beds, pegmatites, and old mine tailings of the Black Hills are by far the most popular rockhounding destinations in the state.

This article will dive deeper into the many great rockhounding sites across the state (along with maps), but I’d like to highlight a few standouts here. Here are 10 of the best rockhounding sites for rocks and minerals in South Dakota:

Rocks and Minerals Found in South Dakota

One of the biggest reasons rockhounds flock to South Dakota is the wide variety of rocks and minerals that can be found here. Most collectors are primarily interested in the Fairburn agates and rose quartz the state is famous for.

South Dakota has a long history of mining gemstones, as well as precious metals like gold and silver. In addition, you can also find many semiprecious stones scattered across the landscape. Quartz-family minerals like agates, jasper, chalcedony, and petrified wood can be found in relative abundance if you know where to look.

There is almost no limit to the number of rock and mineral species you can find in South Dakota, although some are obviously rarer than others. What types of rocks and minerals you can find will largely depend on where you are looking, especially considering how varied its surface geology is.

The most commonly found and collected rocks and minerals in South Dakota are:

  • Agates
  • Rose quartz
  • Petrified wood
  • Beryl
  • Jasper
  • Geodes
  • Jade
  • Quartz crystals
  • Amethyst
  • Chalcedony


If you’ve already found a rock and you’re not sure what it is, I would highly recommend checking out my Practical Rock Identification System. This bundle of information includes a book, videos, and online tools. It is, simply put, the most comprehensive and easy-to-understand rock identification system you’ll find anywhere.

You can also read through my free rock identification guide and mineral identification guide which are filled with useful information and tools.

Where to Rockhound in South Dakota

Important Disclaimer: I have not been to these locations myself, and I do not know if they are currently open for collecting. Use this resource as a guide to get you started. Follow posted signage and always get permission from the landowner to collect.

Through quite a bit of research and cross-referencing of available literature, I have compiled this list of some prospective locations in South Dakota which I would recommend to people looking to do some rockhounding. These are mostly comprised of old mining prospects, washes, streams, and historically known rock and mineral collecting sites. For additional reading, I’d highly recommend these books you can find on Amazon:

Please remember that rock collecting locations are constantly changing. Specimens may become depleted from other collectors, the location may have been built on or altered, locality information in literature may be inaccurate, and property ownership may have changed hands. Joining up with a local rockhounding club for a group trip can often get you access to otherwise off-limits locations like privately owned mines and quarries. There are many rockhounding clubs in South Dakota so you can most likely find one you like nearby.

I have tried to take care not to list locations within National Park boundaries since collecting is illegal there, but please remember that it is up to you to make sure you have permission to collect wherever you are. There is plenty of BLM and National Forest land to collect on in South Dakota which is, in general, open for public use. Still, there may be privately owned mining claims inside those boundaries and you’ll need to get permission to collect on that location.

Though there are many locations listed here, this list is far from exhaustive. A location’s listing here is not a guarantee of accuracy. Be safe, never go underground, and make sure to get permission from the landowner to search for and collect specimens.

South Dakota Rockhounding Sites

Most of the best rockhounding sites in South Dakota are located in the Black Hills. This range in the southwestern corner of the state is most famous for Mount Rushmore, but for us rock and mineral enthusiasts it contains so much more. This area has a long history of mining and is home to some of the best rockhounding anywhere in the United States.

The most notable area for rock and mineral collecting is undoubtedly the agate beds located about 12 miles to the east of Fairburn. This area is home to the world-famous ‘Fairburn agates’ which are coveted by rockhounds all over the world. Their unique, distinctive banding and coloring make them a favorite of lapidary artists and collectors, and a high-quality specimen can be worth quite a bit of money.

Further east from Fairburn is a town called Scenic, which is another prime spot to do some rockhounding. The badlands and ravines surrounding Scenic contain high-quality pieces of quartz-family minerals like carnelian, agate, and chalcedony. Some of the chalcedony found here is a striking shade of blue.

The Black Hills are also home to innumerable old mines and prospects where valuable minerals and ores have been mined for decades. If you can gain access, the tailings of these old mines are a great place to find a variety of collectible material including fluorite, quartz crystals, and many varieties of tourmaline.

Aside from the Black Hills, most of the rest of South Dakota is disappointingly barren of worthwhile rockhouding destinations. The banks and gravels of the Missouri River and its tributaries will sometimes yield petrified and agatized wood.

Where to Find Geodes in South Dakota


Everyone enjoys the prospect of finding their very own geodes out in the wild, and it’s easy to see why. Cracking them open reminds me of opening a Kinder-Egg with a surprise toy inside. You never know what type of crystals or patterns you’re going to find inside and it makes them incredibly exciting.

Thankfully, there are a few places you can find geodes in South Dakota. These geodes tend to be lined with amethyst, quartz crystals, or chalcedony and are typically around baseball-sized. While it is possible to find these geodes for yourself you need to know where to look, because they are only present in certain localities.

The best place to find geodes in South Dakota is Lawrence County, particularly in gravels near Spearfish Canyon and the banks of the Whitewood River. You can also find geodes in Custer County, most notably in Hell Canyon to the north of Jewel Cave and in Pleasant Valley Creek near Pringle.

Tip: Not sure if the rock you’ve found is a geode? Check out my article about how to identify a geode.

For additional places to search for geodes, you may want to expand your search radius and head to a neighboring state like Montana or Wyoming.

Where to Find Agates in South Dakota


I love finding agates because you never know what sort of beautiful patterns and colors they might contain. They are some of the most popular rocks to tumble, and it’s easy to see why with their intricate banding and unique designs.

Agates also happen to be some of the most commonly collected rocks in the United States, including South Dakota. In fact, South Dakota is home to a unique and beautiful variety known as ‘Fairburn Agate’.

Fairburn agates are known for their distinctive red-banded coloring and beautiful ‘fortification’ banding. This gemstone is highly sought after by collectors all over the world for lapidary work and cabbing.

If you’re looking to start collecting rocks in South Dakota, agates are a great place to start. They are widespread and fairly easy to find if you have a general idea of where to look.

In general, the best places to find agates in South Dakota are in the Black Hills in the southwestern part of the state, particularly in Custer County. The famed Fairfield agates are most commonly found in the agate beds to the east of Fairburn but are also found from Rapid City all the way into Nebraska.

Tip: For more info about agates and where to find them, check out my article here.

Rose Quartz is the state mineral of South Dakota, so it’s only natural for us rockhounds to want to find our own specimens to add to our collections. This wonderfully colored pink variety of quartz is one of the most sought-after rocks in the state and is commonly used in lapidary work.

Tip: Check out my Complete Rock Tumbling Guide to make your rocks and gemstones really shine!

There are many locations in South Dakota where you can find rose quartz, and as an added bonus you can often find other interesting rocks and minerals in those same spots including agates, petrified wood, and jasper.

In general, the best places to find rose quartz in South Dakota are in the Black Hills in the southwestern part of the state. In particular, the most popular locations for rose quartz are in pegmatite outcrops east of Custer and in exposures north of the highway east of Pringle.

South Dakota Rockhounding Laws & Regulations

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 accurate information for every location on this page. However, I have compiled a list of resources here so that you may investigate and obtain permission for any locations (found here or elsewhere) for yourself.

Public Land Resources

I have written entire articles which cover the rockhounding laws and regulations for nearly every type of public land you can think of. I encourage you to check them out if you are curious about the legalities of rock and mineral collecting.

To determine what type of public land a particular location is on, I would recommend starting with the maps from South Dakota’s Game, Fish & Parks Department.

Private Land Resources

As with most states, each county in South Dakota will have records of who owns each piece of property. You can also usually get the landowner’s name and address by visiting the county records office. I would probably start by checking with the South Dakota Department of Revenue and getting whatever contact information you can for the landowner.

Sources & Further Reading

The locations and information contained in this article are my interpretations of potentially interesting rockhounding sites, primarily derived from academic papers and other outside sources. I have listed several potentially useful resources below if you would like to explore further.
