How to Identify American Indian Arrowheads: A Complete Identification Guide?

Compare any point’s find location, shape class, notch and stem form, flaking, and base treatment against a regional typology reference to narrow it to a named type.

Digging one out of a creek bank is the easy part. Naming it is where most collectors stall, and the mistake that cost them the identification is usually the same: they walk straight to a shape chart without writing down where the point came from. Location and shape, checked together in that order, turn a tray of unknown stones into a short list of real candidates.

Why Your Find Location Comes Before Shape

Region narrows the possibilities faster than any other single fact, so record it first. Point styles were made in specific places and specific eras, and a regional typology reference filtered by state or county can cut a list of a thousand types down to a handful worth comparing.

The North American Arrowhead Identification Guide organizes points by shape groups — side notch, corner notch, basal notch, contracting stem, straight stem, expanding stem, lanceolate, bifurcated, ovoid, and triangle — and regional filtering works with those groups, not against them. Note the county and the land type before you clean a thing.

Which Physical Features Actually Decide The Type

Stem form and notch placement are the two features that separate most named types from their neighbors. Work through the point in a fixed order so you never skip a diagnostic feature.

• Overall outline — the silhouette from base to tip.
• Stemmed or stemless — does the base narrow into a stem at all?
• Stem direction — contracting, straight, or expanding.
• Notch type — side, corner, or basal.
• Base treatment — ground smooth, concave, straight, or broken.
• Measurements — length, width, thickness, in millimeters.

One practical field guide splits the whole category into dart points and arrow points. Dart points run larger and older; arrow points run smaller and belong to bow-and-arrow use. That single split removes a lot of bad matches before shape even enters the picture.

Flaking, Patina, And Wear: Real Or Just A Rock?

Authentic worked stone shows controlled flaking that natural breakage cannot fake. Percussion flaking shapes the point, pressure flaking finishes the edge, and the flake scars sit in deliberate, overlapping rows rather than random fractures.

Then look at how time treated it. Impact fractures, edge resharpening, the asymmetry that comes from repeated use, and basal grinding are all normal on a genuine point. Weathering and patina should look consistent across the whole surface. A fresh chip that exposes bright new stone in the middle of a patinated piece is a warning sign, and so is symmetry with no wear at all — plenty of modern reproductions are cleaner than anything made a few thousand years ago.

The everyday mistakes worth naming: assuming every sharp stone flake is an arrowhead, ignoring the find spot, and judging on symmetry alone instead of flaking, patina, and use wear together.

Identification references tie each named type to a cultural period, so a match to a published type chart is part of the process, not a shortcut around it. The Projectile Point Identification Guide’s national search lets you filter by shape and region together, which is the fastest way to reach a short list of candidates worth studying. For collectors who would rather start with finished examples in hand, these identified arrowhead examples and displays show what correctly typed points actually look like side by side.

Tools That Make The Comparison Workable

1. Photograph the point against a plain background and note where it was found.
2. Measure length, width, thickness, notch type, stem form, and base treatment.
3. Compare the shape against a regional typology database or guide.
4. Check flaking, patina, and wear to judge whether it is genuinely worked stone.
5. If it sits in context with other artifacts or features, document it and report the find instead of disturbing the site.

The Legal Side Nobody Mentions Until It Matters

Rules vary by state and by who owns the land, so check before you dig. Mississippi law declares certain archaeological sites and artifacts state property and requires permits for excavation, and it requires written landowner permission to hunt for artifacts there. Federal and tribal land is more sensitive still — an ATADA summary of tribal art law notes that artifacts illegally taken from federal or Indian lands are unlawful to trade, and it treats surface-found arrowheads differently from excavated ones.

The safe practice is simple: leave artifacts undisturbed where they lie, document the location, and contact historic preservation authorities or tribes when a find looks significant. Identification does not require digging. It requires good notes, honest measurements, and a reliable regional reference.
