Prime Colonial Sites Worth Exploring
Where should metal detecting enthusiasts and archaeologists focus their attention when exploring America’s colonial past? Virginia’s Chesapeake region offers exceptional opportunities, particularly at Kippax Plantation, where 17th-century trading activities left substantial archaeological deposits.
Jamestown’s ongoing excavations demonstrate how systematic metal detection reveals critical historical layers, including recent fire damage discoveries. Metal fragility remains a significant concern in these environments, as soil acidity in coastal regions accelerates artifact degradation.
Historic St. Mary’s City provides controlled access for research, with continuous archaeological programs since 1634. Fort Raleigh‘s earthen fortifications yielded America’s first scientific laboratory through National Geographic-funded excavations. Investigators at Fort Raleigh uncovered pottery and copper jewelry that provide crucial evidence linking artifacts to the lost Roanoke Colony.
Colonial Williamsburg’s burned barracks demonstrate how metal artifacts survive catastrophic events. Mount Vernon’s reconstructed mill and distillery showcase 18th-century industrial archaeology alongside the main plantation complex. You’ll find these sites balance preservation requirements with legitimate archaeological exploration, offering documented contexts for recovered materials.
What You Can Expect to Find
Understanding potential recoveries becomes pragmatic once you’ve pinpointed promising colonial spots. Archaeological proof shows that Spanish colonial coins are the most commonly recovered currency.
With cob pieces and pre-1750s Spanish reales appearing consistently across Atlantic coastal sites. You’ll also find British coinage, Portuguese reis, and occasionally elusive pine tree shillings from New England settlements.
Clothing hardware dominates most finds—expect 20+ buttons, multiple shoe buckles, and various brass fasteners per productive area. Precious metal discoveries remain uncommon but achievable: 1700s silver brooches, gold rings with engravings, and complete cuff link sets reward persistent effort.
Base metal artifacts mainly include cut nails and iron construction hardware. Colonial-era toy cannons crafted from bronze alloy occasionally surface, providing evidence of children’s play items from the period. Farm-related relics like ox shoes and horse tack fragments indicate agricultural activity zones where colonial settlers worked the land.
Achievement depends on choosing suitable metal detector models for soil mineralization conditions while systematically exploring identified colonial activity zones.
Equipment and Search Methods That Work
Your success at colonial sites depends on matching multi-frequency detectors to mineralized soil conditions prevalent across the original thirteen colonies, as these settings enable discrimination between period artifacts and modern aluminum debris.
Historical maps from local societies reveal creek crossings, colonial roads, and troop movement corridors that concentrate recoverable artifacts in predictable patterns.
Systematic coverage of these high-probability features—including visible wagon ruts and documented skirmish locations—requires multiple visits with varied coil configurations to extract artifacts missed during previous searches. Small coils provide precise target identification in confined spaces around cellar holes and structural remains where colonial-era buttons and coins typically cluster. Sensitive pinpointers paired with proper digging tools allow surgical precision during extraction, preventing damage to fragile colonial-era items that might otherwise crumble under careless recovery techniques.
Optimal Detector Frequency Settings
When searching colonial-era sites, selecting the proper frequency range dramatically affects your recovery rate of period artifacts. You’ll achieve ideal results operating between 5-10 kHz, as these lower frequencies penetrate deeper into soil layers where colonial objects rest 1-2+ feet underground.
Frequency calibration within this range maximizes sensitivity to iron implements, tools, and hardware—predominant materials at colonial locations.
Ground mineralization presents significant challenges at centuries-old settlement sites. Operating below 10 kHz minimizes false signals caused by mineral-rich soil, though you’ll still need active ground balancing when shifting between different soil composition zones.
Begin detection at 70-80% factory sensitivity settings, then employ the Threshold of Stability Method: gradually increase sensitivity until false signals emerge, then reduce slightly to establish your ideal operating point. This low-frequency range provides stable operation in the mineralized soils typical of colonial settlement areas, reducing interference that would otherwise obscure genuine target signals from buried artifacts. Consider using a larger coil design to maximize ground penetration at these lower frequencies, which naturally pairs with coil sizes that reach the depths where colonial artifacts typically settle.
Reading Historical Land Maps
Although colonial-era settlements left minimal surface traces after centuries of agricultural use and development, systematic analysis of historical land maps enables detectorists to identify artifact concentration zones with precision rates exceeding random search patterns by 300-400%.
You’ll extract maximum value from 18th-century maps by focusing on creek crossings and colonial roads where troop movements concentrated artifacts. USGS turn-of-the-century maps reveal building footprints you can overlay with LIDAR imagery to locate hidden foundations.
Map symbology indicating rock walls predating roads suggests pre-1760 settlement features worth investigating. Mills Atlas maps document unlisted colonial permissions on private properties.
When conducting landscape analysis, compare 1858 occupation maps with modern terrain to pinpoint abandoned homesteads. Document chimney stone piles and house footprints, then secure landowner permission by sharing your research findings before detecting. Metal detectors enable rapid discovery of artifacts across large survey areas, transforming site coverage capabilities that previously required extensive excavation methods. Remote locations with limited previous exploration often yield the most significant archaeological discoveries, as these sites preserve intact artifact distributions and structural remains.
Targeting High-Probability Ground Features
Multi-frequency metal detectors operating between 7-14kHz provide the technological foundation for successful colonial artifact recovery, particularly in the iron-contaminated and mineralized soils that characterize 18th-century settlement sites.
You’ll maximize detection depth by targeting creek crossings along colonial-era roads, where water erosion concentrates copper coins and flat buttons in predictable strata.
Wagon trails and ruts yield King George II/III coins when you conduct systematic grid searches with discrimination settings that eliminate modern aluminum interference.
Stone chimney stacks and iron bed nail concentrations mark high-probability zones requiring 5-inch coils for cluttered areas and 12-inch coils for field coverage.
Soil analysis of sandy topsoil-to-hard-clay variations guides your plug excavation depth to 12-13 inches.
GPS logging of fired lead shot distributions documents troop movements before artifact restoration begins.
Understanding the Historical Timeline

You’ll need to establish chronological markers to interpret your finds correctly, as colonial sites span over 400 years of distinct settlement patterns and material culture.
Understanding that Columbus established the first Spanish colony in 1492, British forts operated in Georgia from 1730-1750, and currency evolved from Spanish COBs to Rosa Americana coins helps you date artifacts within specific decades.
Trace element analysis through X-ray fluorescence spectroscopy now reveals that manganese concentrations in 16th-century Spanish iron differ markedly from later periods, providing forensic dating beyond stylistic assessment alone.
Key Colonial Settlement Dates
When planning metal detecting expeditions at colonial sites, understanding the chronological layering of settlements directly impacts your search strategy and artifact expectations.
St. Augustine’s 1565 establishment predates Jamestown by 42 years, offering Spanish colonial artifacts distinct from English settlements. You’ll find Dutch materials in former New Netherland territories (1624-1664), while French colonial sites like New Orleans (1718) and Arkansas Post (1686) yield different material cultures entirely.
Historical artifact identification requires recognizing these temporal and cultural distinctions—a 1620s Plymouth site differs substantially from 1730s Georgia settlements. Your detecting depth and target selection must account for sequential occupations: English superseding Dutch in New York, or later American expansion overlaying French territories.
Colonial site preservation demands documenting finds with precise chronological context, ensuring artifacts contribute meaningfully to archaeological records.
Currency Evolution Through Centuries
Understanding the monetary systems that preceded American standardization fundamentally transforms how you interpret colonial-era finds, as the chaotic currency landscape of the 17th and 18th centuries produced a remarkable diversity of coins and tokens across archaeological sites.
Ancient artifacts you’ll discover include:
- Spanish dollars and foreign coins (1600s-1700s) – Trade relics from West Indies commerce that served as unofficial currency
- Massachusetts Pine Tree shillings (1652+) – America’s first colonial coinage, all deceptively dated 1652
- Continental currency remnants (1775-1781) – Revolutionary War bills that depreciated to worthlessness by 1781
- Post-1792 standardized coins – Federal currency following the Coinage Act’s decimal system
This monetary chaos means you’re not just finding coins—you’re uncovering evidence of colonial America’s struggle for economic independence.
Before you swing a detector over colonial-era ground, federal statutes establish clear boundaries that carry significant legal consequences. The American Antiquities Act and ARPA prohibit unauthorized excavation on federal lands, with penalties including equipment confiscation and criminal charges.
Legal compliance begins with identifying site ownership—private colonial homesites offer maximum autonomy once you’ve secured written landowner permission specifying access areas and artifact handling.
Private colonial properties provide detectorists greatest operational freedom following documented landowner authorization that defines boundaries and artifact protocols.
The permission process requires documented consent before detecting any colonial site. State regulations add another layer; Texas mandates antiquities permits for public property artifact collection.
You’ll navigate these frameworks by researching historical site protections, submitting detailed requests demonstrating ARPA awareness, and confirming property boundaries. This methodical approach protects both archaeological heritage and your freedom to pursue responsible detecting where legitimately authorized.
Identifying Promising Ground Features

Armed with proper authorization, your detector’s effectiveness depends entirely on reading the landscape through a colonial settler’s perspective. Water-proximate zones—creeks, ditches, and lowlands—concentrated daily activities where trading and survival necessitated proximity to resources. These artifact hotspots yield coins, buttons, and trade goods where soil preservation remains ideal.
Priority ground features include:
- Field-to-forest boundaries marking settlement expansion with structural remnants
- Tidal zones at ultra-low tide exposing otherwise inaccessible artifact layers
- Dark, moisture-retaining lowland soil preserving maker’s marks and fine metalwork details
- Clay subsurface strata (12-13 inches depth) where items naturally settled and concentrated
Transitional terrain where sandy topsoil meets clay creates natural repositories.
Rolling hardwood forests and marshy areas with leaf-covered floors protect colonial-era deposits from modern disturbance, rewarding systematic investigation patterns.
Documented Treasure Recoveries
When colonial-era metal detecting yields become documented through verifiable recoveries, they establish empirical baselines for artifact distribution patterns across different site typologies.
You’ll find Jamestown excavations produced 1600s English, Spanish, and Dutch coinage alongside Native American trade goods, while Cape Cod sites yielded Revolutionary War artifacts including musket balls and uniform insignia.
Riverbed dives documented 1700s gold rings and complete cuff link sets, demonstrating preservation in aquatic environments.
Even “hunted-out” locations produced cut Spanish silver from the 1720s-1730s when you employ systematic grid patterns.
Multi-site recoveries confirmed King George coinage distribution across colonial territories.
These documented finds validate equipment performance beyond standard metal detector warranties, providing hunting season tips grounded in empirical recovery data rather than speculation.
Best Practices for Colonial Site Research

Successful colonial site research demands systematic archival investigation that establishes documentary baselines before you invest resources in fieldwork.
Historical records narrow potential locations, enabling efficient deployment of survey methods across expansive landscapes.
You’ll maximize discoveries by implementing structured protocols:
- Systematic grid testing at standard intervals generates artifact concentration maps that reveal settlement patterns.
- Metal hygiene protocols during recovery prevent corrosion damage to ferrous artifacts from contamination.
- Relic preservation techniques, including proper cleaning, documentation, and storage, maintain artifact integrity for analysis.
- Dimensional analysis of recovered objects enables comparison with documented manufacturing techniques and production periods.
Ground-penetrating radar and drone surveys complement traditional shovel testing, detecting buried foundations before excavation.
Retain all artifacts—even modern materials—as they contextualize site chronology.
This evidence-based approach respects archaeological integrity while pursuing historical knowledge independently.
Frequently Asked Questions
