Check current weather and road conditions before heading out, especially for remote BLM and Forest Service roads.
Where to Find Fairburn Agate in South Dakota
South Dakota designated the Fairburn agate as its state gemstone in 1966. Fairburn agates are fortification agates — concentric, angular banding in vivid reds, oranges, yellows, and whites. They are among the most sought-after and valuable agates in the world. Originally formed in Precambrian rock, they were weathered out and deposited in Tertiary and Quaternary gravels across the southern Black Hills and adjacent prairie.
Top sites:
- Fairburn area, Custer County — The namesake locality. Agates in gravel deposits and grassland surface. Most land is private ranch — ask permission.
- Buffalo Gap National Grassland — Public land. Fairburn agates and prairie agates in surface gravels and eroded badlands. Surface collecting.
Fairburn agates are small (most are under 3 inches) but their tight, vivid banding makes them valuable — premium specimens sell for hundreds to thousands of dollars. They are hard to find (that is part of the value). Walk slowly, scan the ground, and wet any promising agate to check the banding pattern. The best hunting is after rain on bare prairie ground. Patience is the primary tool.
Where to Find Rose Quartz in South Dakota
The Black Hills of South Dakota produce rose quartz of exceptional quality. The pegmatites near Custer (Custer County) include some of the largest and finest rose quartz deposits in North America. Rose quartz forms as massive (not crystallized) pink quartz in the core zones of lithium-rich pegmatites.
Top sites:
- Bull Moose Mine, Custer County — Rose quartz in pegmatite. Check access status — some pegmatite quarries in the area allow collecting by arrangement.
- Scott Mine / Hwy 16A area, Custer County — Rose quartz and beryl in pegmatite. Road cuts and mine dumps.
Black Hills rose quartz is translucent pink to deep rose. The color comes from trace amounts of titanium and manganese. Massive pieces (several pounds) are common in productive pegmatites. The material takes an excellent polish for cabochons, spheres, and carvings. Distinguish from pink feldspar (rose quartz has no cleavage and is harder — hardness 7 vs. 6). Star rose quartz (with asterism from rutile inclusions) occurs rarely.
Where to Find Gold in South Dakota
The Black Hills gold rush of 1874 made Deadwood famous and built the Homestake Mine — once the largest and deepest gold mine in the Western Hemisphere (now a physics laboratory). Recreational gold panning is legal on designated National Forest land in the Black Hills.
Top sites:
- French Creek, Custer State Park — Where gold was first discovered in the Black Hills. Panning is allowed in designated areas of the park.
- Black Hills National Forest streams — Gold panning and hand sluicing on NF land. Fine placer gold in stream gravels draining the Precambrian gold-bearing schist.
Black Hills placer gold is fine — flour to flake. The gold occurs in Precambrian schist and was concentrated in stream placers. Work bedrock crevices at low water for the best results. Custer State Park allows limited panning — check park rules. The Wade Hampton Creek and Rapid Creek drainages are productive recreational areas on National Forest land.
South Dakota Rockhounding Laws & Public Land Rules
BLM Land
South Dakota has limited BLM land, primarily the Buffalo Gap and Fort Pierre National Grasslands. Recreational collecting is allowed for personal, non-commercial use.
National Forests
Black Hills National Forest allows collecting for personal use. Gold panning is permitted in NF streams.
State Parks
Custer State Park allows limited gold panning. Collecting is generally restricted in other state parks — check individual rules.
Collection Limits
BLM: 25 lbs per day plus one specimen. National Forest: casual use provisions.
What's Protected
Badlands National Park, Wind Cave National Park, Jewel Cave National Monument, and Mount Rushmore National Memorial prohibit all collecting. Active mining claims in the Black Hills are common — check claim status.
South Dakota has two collecting zones: the Black Hills (gold, pegmatite minerals, rose quartz) and the prairie/badlands (Fairburn agates, fossils). The Black Hills are well-roaded and accessible. The badlands require walking and patience. Rattlesnakes are present in both zones from May through September.

- Safety glasses — required any time you swing a hammer
- Chisels — cold chisels for splitting seams and extracting crystals
- Bucket and bags — 5-gallon bucket, zip-lock bags for specimens
- GPS device or phone app — cell service is unreliable at most sites
- 1 gallon of water per person — minimum, more in summer
- Sturdy boots — ankle support for loose talus and mine tailings
- Field guide — a regional mineral identification guide for South Dakota
Always respect private property, follow Leave No Trace principles, and check current regulations before collecting. On BLM land, the general rule is 25 lbs per day plus one specimen for personal, non-commercial use.
