Their diversity has been variously interpreted as being associated with specific time periods, particular geographical ranges, ethnic identities, and tool functions. Several different approaches have been applied to classifying projectile points in order to extract their interpretive value. The links above lead to summaries of the results of several of those approaches. Among the detailed classifications of substantial collections of points from Baja California are studies by William C. Massey (1966), Emma Lou Davis (1968), Eric W. Ritter (1979), Kelli Carmean (1994), Eduardo Seraf\u00edn Esquivel (1995), Ritter and Julie Burcell (1998), Rub\u00e9n Garc\u00eda (2013) and Erika Moranchel (2014).<\/p>\n<style>#sp-ea-185 .spcollapsing { height: 0; overflow: hidden; transition-property: height;transition-duration: 300ms;}#sp-ea-185.sp-easy-accordion>.sp-ea-single {margin-bottom: 10px; border: 1px solid #e2e2e2; }#sp-ea-185.sp-easy-accordion>.sp-ea-single>.ea-header a {color: #444;}#sp-ea-185.sp-easy-accordion>.sp-ea-single>.sp-collapse>.ea-body {background: #fff; color: #444;}#sp-ea-185.sp-easy-accordion>.sp-ea-single {background: #eee;}#sp-ea-185.sp-easy-accordion>.sp-ea-single>.ea-header a .ea-expand-icon { float: left; color: #444;font-size: 16px;}<\/style><div id=\"sp_easy_accordion-1722025630\"><div id=\"sp-ea-185\" class=\"sp-ea-one sp-easy-accordion\" data-ea-active=\"ea-click\" data-ea-mode=\"vertical\" data-preloader=\"\" data-scroll-active-item=\"\" data-offset-to-scroll=\"0\"><div class=\"ea-card sp-ea-single\"><h3 class=\"ea-header\"><a class=\"collapsed\" id=\"ea-header-1850\" role=\"button\" data-sptoggle=\"spcollapse\" data-sptarget=\"#collapse1850\" aria-controls=\"collapse1850\" href=\"#\" aria-expanded=\"false\" tabindex=\"0\"><i aria-hidden=\"true\" role=\"presentation\" class=\"ea-expand-icon eap-icon-ea-expand-plus\"><\/i> Named Types<\/a><\/h3><div class=\"sp-collapse spcollapse spcollapse\" id=\"collapse1850\" data-parent=\"#sp-ea-185\" role=\"region\" aria-labelledby=\"ea-header-1850\"> <div class=\"ea-body\"><p>Named projectile point types have usually been defined intuitively, based on their similarity to point forms that were found at a type site or in a type area. At least 29 named types have been reported from Baja California. Of these, about half were originally named on the peninsula, while the remainder were originally designated elsewhere in North America.<\/p><p><b>AMARGOSA.<\/b>\u00a0Malcolm Rogers designated two relatively late phases in the Colorado and Mojave deserts of southern California and adjacent areas as the Amargosa industry, and he noted a variety of large and small projectile point forms (many of which would be classified as Elko points) that were associated with this industry. Erika Moranchel applied the term of Amargosa points to three small, triangular points in northern and central Baja California, two of which had expanding stems and the third had a concave base.

The type has been reported as occurring throughout much of North America, with a time range in the terminal Pleistocene between ca. 11,500 and 9000 B.C. Within Baja California, finds so far have been recovered primarily from the central portion of the peninsula (Aschmann 1952; Des Lauriers 2008; Guti\u00e9rrez and Hyland 2002; Hyland 1997, 2006; Hyland and Guti\u00e9rrez 1995), but one specimen from the Bajamar-Jatay site complex on the northwestern coast has also been reported (Garc\u00eda 2013; Garc\u00eda and Ovilla 2017).

They appear to be fully equivalent to the points designated as Cottonwood Triangular and perhaps as Desert Side-notched in the western U.S., with the serrated variety corresponding to the Dos Cabezas Serrated type (Wilke and McDonald 1986) in the U.S. These points seem to mark the local appearance of the bow and arrow, and to date from roughly A.D. 1000 into the historic period. They are relatively abundant throughout central Baja California. The late prehistoric Comond\u00fa culture was defined by William C. Massey (1966), and the designation of the points associated with it as Comond\u00fa points was begun by Eric W.

Their distribution includes most of the western United States, and they are associated with a time period subsequent to the introduction of the bow and arrow, perhaps after about A.D. 1000. The points are typically small, with no stems (triangular), concave to straight bases, and straight sides.\u00a0Cottonwood points have been reported from northern Baja California; in central and southern Baja California, similar points have generally been classified as Comond\u00fa, although Eduardo Seraf\u00edn Esquivel (1995) applied the designation of Cottonwood to central Baja California points.<\/p><p><b><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-189 alignright\" src=\"http:\/\/gvu.ocl.mybluehost.me\/baja-and-california\/wp-content\/uploads\/2024\/07\/points.descanso.gif\" alt=\"\" width=\"61\" height=\"150\" \/>DESCANSO.<\/b>\u00a0This type was defined by Andrew R. Pigniolo and Antonio Porcayo Michelini (2009), based on finds within a relatively small area in northwestern Baja California and southwestern California (see also Garc\u00eda 2013).

The type was defined by Philip J. Wilke and Meg McDonald at Indian Hill Rockshelter near Dos Cabezas near the southern extreme of California. Erika Moranchel assigned two small, serrated, convex-based points in northern Baja California to this type (McDonald 1992; Moranchel 2014; Wilke et al. 1986).<\/p><p><b>EL ARCO.<\/b>\u00a0This designation was applied by Erika Moranchel to three large point fragments found in the general area of El Arco, in central Baja California.

It has been applied to large, corner-notched, eared, or split-stem points. The forms are relatively common in central Baja California, and they are also reported from the peninsula's northwest region. Time spans suggested for the Elko series outside the peninsula include ca. 6000 B.C. to A.D. 800 (Jennings 1986:117) and ca. 1300 B.C. to A.D. 700 (Thomas 1981:20). Ritter (2006b:143) suggested a time span between ca. 6000-5000 B.C. and A.D. 400 for \u201cElko-like\u201d points on the peninsula.<\/p><p><b>EL ZACATECO.<\/b>\u00a0Two small, triangular point fragments with concave bases and single lateral notches were assigned to this type by Erika Moranchel.

Hyland (1997) lumped this type within the Elko series; however, the small size of Guajadem\u00ed points would seem to make that assignment questionable. In some respects, the Guajadem\u00ed points seem similar to Rose Spring points, although the latter more commonly have straight or convex bases (Thomas 1981:20). Ritter (2006a:111) considered the Guajadem\u00ed Split-stem type as one of the hallmarks of the late period between ca.

It includes triangular points with concave or straight bases but occurring in both large and small sizes. Ritter (2006b:142-143) suggested that Guerrero Negro points \u201cmay possibly have served as harpoon tip insets; their distribution appears to be limited to coastal locations in west-central Baja California.\u201d <img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-196 alignright\" src=\"http:\/\/gvu.ocl.mybluehost.me\/baja-and-california\/wp-content\/uploads\/2024\/07\/points.gypsum.gif\" alt=\"\" width=\"73\" height=\"129\" \/>However, large, triangular points have also been reported from sites elsewhere in Baja California, including interior locations (e.g., Hyland 1997:300).<\/p><p><b>GYPSUM CAVE.<\/b> The Gypsum type is based on points recovered by Mark R.

These points are generally dated to the early Holocene, perhaps also extending back into the late Pleistocene. The large points have weak shoulders and long, contracting, rounded stems.

These studies were done by Eric W. Ritter (1979), using points recovered in the Bah\u00eda Concepci\u00f3n area, and by Kelli Carmean (1994), using points in the Castald\u00ed collection from central and southern Baja California that had been previously reported and analyzed by William C. Massey (1966).<\/p><p><b>Eric W. Ritter (1979).<\/b>\u00a0Ritter's study involved analysis of a sample of 90 points (excluding small triangular side-notched or serrated points, and points without modified stems). About two dozen metrical and non-metrical attributes were recorded, and a dendrogram was generated, grouping the points statistically into seven clusters, as well as sub-clusters. However, several of the clusters were assessed intuitively as not being meaningful. Ritter (1979:173) concluded, \"It seems clear this computerized technique as used here is not very helpful.\" Consequently, he adopted instead a more traditional, intuitive classification of the points into named types.<\/p><p><b>Kelli Carmean (1994).<\/b>\u00a0Carmean reanalized 137 points from the Castald\u00ed collection. She settled on six attributes to use in the analysis:<\/p><ul><li>point length<\/li><li>distal shoulder angle, based on the orientation of the segment of the point extending distally from the distal end of the stem (shoulder orientation)<\/li><li>proximal shoulder angle, based on the orientation of the segment of the point extending proximally from the distal end of the stem (stem orientation)<\/li><li>notch opening index, based on the angle between the segments extending distally and proximally from the distal end of the stem<\/li><li>neck width<\/li><li>stem length<\/li><\/ul><p>Using these variables, Carmean distinguished eight statistical clusters. To these she added three more clusters (numbers 9 through 11, below), based on judgmentally selected nominal variables. The total of 11 clusters included:<\/p><ul><li>Cluster 1 - \"small, high-notched\" (n = 26). (Note that this cluster included \"small\" points with measured lengths up to 5.9 cm and point fragments that were evidently originally even larger than that. It included a classic \"Desert side-notched\" point, as well as large, stemmed points.)<\/li><li>Cluster 2 - \"small, leaf-shaped\" (n = 49). (Note that this cluster included \"small\" points up to 7.5 cm in length, as well as triangular points.)<\/li><li>Cluster 3 - \"medium, low-notched\" (n = 11).<\/li><li>Cluster 4 - \"stretched-diamond\" (n = 2).<\/li><li>Cluster 5 - \"large La Paz\" (n = 3).

(Note that the \"small, high-notched\" and \"medium, high-notched\" clusters overlap substantially in their size ranges.)<\/li><li>Cluster 8 - \"small La Paz\" (n = 8).<\/li><li>Cluster 9 - \"serrated\" (n = 10).

Some attributes, individually or in small sets, are hypothesized to have been restricted in their chronological, geographical, or functional distributions. However, the current state of archaeological research in Baja California usually does not yet make it possible to confirm these hypotheses.<\/p><p>In general, attribute classifications are not based on any clear-cut discontinuities. Instead, the differences are gradational, and, to some extent, the divisions are arbitrary. The interpretive value of such classifications is likely to be statistical and probabilistic, rather than being definitive at the level of the individual specimen. It may be possible to say with some confidence, for instance, that small points, or expanding-stem points, or some other attribute category, are likely to be associated with a particular time period, a cultural tradition, or a function. But it is usually not possible to say with complete confidence that an individual specimen must pertain to that period, tradition, or function.<\/p><h5>Attributes with Potential Interpretive Significance<\/h5><p><b>Point Size<\/b><\/p><p>The size of projectile points may be one of the most interpretively useful attributes. It appears to be strongly correlated with chronology and point function. Specifically, small points may postdate the introduction of the bow and arrow. The timing of that introduction in Baja California is not well established, and it may have varied substantially on a north-south gradient. The bow and arrow were present in western North America by ca. A.D. 400, but they may not have reached the Cape Region until the early historic period.<\/p><p>To measure point size, four possible dimensions are length, width, thickness, and weight; combinations of those are also possible. Aerodynamically, weight seems to be the most logical choice, in that heavy points would likely be unstable on arrows. Franklin Fenenga (1953) looked at a large sample of projectile points from North American sites and found a marked dip in the frequency of weights at 4.0 g. Such a dip is what one might expect if small and large points represented distinct (but overlapping) populations reflecting different technologies. However, this dip is not replicated in a collection of weight frequencies for whole points from California and the Great Basin (Justice 2002:422-442). In the latter data set, the most plausible dip occurs at about 2.2 g. To distinguish late prehistoric points in the Great Basin, David Hurst Thomas (1981) suggested a cutoff of 1.5 g; this weight does not correspond to any dip in recorded point frequencies for Alta California and the Great Basin.<\/p><p>A drawback in using weight as an index for point size is that weights have frequently not been reported for Baja California point assemblages, and weights are less likely than linear dimensions to be measured in the field during non-collecting studies. Graphic illustrations of points include usable information on linear dimensions but not on weights. In some archaeological reports, it may not be clear whether a recorded weight refers to a point fragment or to a whole specimen. For many point fragments, it is possible to extrapolate an original linear measurement, but extrapolating the original weight from a fragment is more problematic.<\/p><p>Alternatives to weight as indices for point size include length, width, and thickness. For thickness, the problem of measurement error is probably most severe. Thickness is not documented for many points that are only recorded through plan-view photographs or drawings. Width may have an advantage of being less subject than length to alteration through point reworking after breakage (cf. Bettinger and Eerkens 1999), but measurement error is probably also higher for width than with length. On balance, length may be the most convenient index of point size.<\/p><p>Plotting the frequencies of length measurements on a sample of points from Baja California, Alta California, and the Great Basin does not suggest any dip in length frequencies that might naturally distinguish large from small populations (Carmean 1994b; Justice 2002; Ritter and Burcell 1998). While point length is correlated with point size in the sample of Alta California and Great Basin points, the relationship is only a rough one. Consequently, defining a dividing line between large and small points based on length is necessarily rather arbitrary at this stage of investigations. Thomas (1981:25) used a cutoff of 3 cm. This may be the most expedient index to use at present.<\/p><p><a name=\"stem\"><\/a><b>Stem Morphology<\/b><\/p><p>This attribute has figured very prominently in most point typologies. Functionally, it likely relates to the manner in which the points were fastened to the projectile shafts or foreshafts. Six general categories of stem forms may be suggested:<\/p><ul><li>Triangular (i.e., no stems). These points are widest at their proximal end and are not side-notched.<\/li><li>No shoulders. These points become narrower toward the proximal end, but there is not a marked contraction immediately after their greatest width. Most such points would also be labeled as \u201cleaf-shaped,\u201d \u201cfoliate,\u201d or \u201cdiamond-shaped.\u201d<\/li><li>Wide stem. These points are widest at the proximal end but contain notches on the blade edges near the proximal end. Such points would also be labeled \u201cside-notched.\u201d<\/li><li>Expanding stem. These points are widest at their shoulders, but their stem expands proximally below the shoulders.<\/li><li>Straight stem. The stem on these points neither expands nor contracts; the lateral edges of the stem are parallel to the points\u2019 axis.<\/li><li>Contracting stem. The lateral edges of the stem on these points narrow proximally.<\/li><\/ul><p>Other attributes relating to point stems have been suggested as significant, at least in some cases. These include stem width and stem length, considered either absolutely or relative to overall point length.<\/p><p><a name=\"base\"><\/a><b>Base Morphology<\/b><\/p><p>This attribute has been incorporated in many typologies. Functionally, it may relate to the ways in which points were joined to projectile shafts or foreshafts. The proximal edges of points may be classified as concave, straight, convex, or pointed.<\/p><p><a name=\"shoulder\"><\/a><b>Shoulder Morphology<\/b><\/p><p>Occasionally, typologies have taken note of whether points' shoulders are sharp or rounded. Also of interest has been whether the proximal edges below the shoulders slope toward the point's proximal end, are perpendicular to the points\u2019 log axis, or slope back toward the distal end (i.e., are barbed). Points with barbed shoulders may have been designed to be more resistant to becoming dislodged from a wound.<\/p><p><a name=\"blade\"><\/a><b>Blade Morphology<\/b><\/p><p>The distal edges of a point may be noted as straight, convex, or (much more rarely) concave. Probably more important is the presence or absence of serration or notching. Serrated edges have sharp projections where the indentations overlap; notched points have flat portions of blade between the indentations. Blade serration and notching may have served to increase tissue damage during penetration. A more speculative suggestion is that they may have been designs used to mark ownership of the point.<\/p><p><a name=\"width\"><\/a><b>Width-to-Length Ratio<\/b><\/p><p>A width-to-length ratio that is either atypically high or low might be suggestive of point reworking after use damage. In cases of extreme point narrowness, such points may have been quite fragile, perhaps suggesting that they had social or ideological functions rather than being used on utilitarian projectiles.<\/p><p><a name=\"thickness\"><\/a><b>Thickness-to-Width Ratio<\/b><\/p><p>Atypically thick points may have been extensively reworked, or they may have served some particular function. Atypically thin points may have been excessively fragile and might have served other functions, as in the case of atypically narrow points.<\/p><p><a name=\"flaking\"><\/a><b>Flaking Techniques<\/b><\/p><p>Crude or refined flaking, and the use of percussion or pressure flaking techniques, have sometimes been distinguished. Eduardo Seraf\u00edn Esquivel (1995) classified the flaking of Baja California points as irregular or regular, and in the latter case distinguished wide (&gt;4 mm), medium (2-4 mm), and narrow (&lt;2 mm) flaking. A specific flaking technique of interpretive importance is the removal of fluting flakes from the base of some terminal Pleistocene (\u201cClovis\u201d) points.<\/p><p><a name=\"material\"><\/a><b>Material Type<\/b><\/p><p>The lithic (or non-lithic) material from which a point was manufactured is an attribute of evident potential interpretive significance. While material type has typically been noted in point descriptions, this attribute has not usually been incorporated into type definitions. Materials were variously local or imported, and they may have been selected on the basis of such considerations as their relative availability, nodule size, workability, strength, and durability.<\/p><hr \/><p><a name=\"occurrence\"><\/a><\/p><h5>Reported Attribute Occurrences<\/h5><p>This tabulation draws upon the existing archaeological literature on Baja California projectile points, which relates primarily to the central portion of the peninsula.

Their diversity has been variously interpreted as being associated with specific time periods, particular geographical ranges, ethnic identities, and tool functions. Several different approaches have been applied to classifying projectile points in order to extract their interpretive value. The links above lead to summaries of the results of several of those approaches. Among the detailed classifications of substantial collections of points from Baja California are studies by William C. Massey (1966), Emma Lou Davis (1968), Eric W. Ritter (1979), Kelli Carmean (1994), Eduardo Seraf\u00edn Esquivel (1995), Ritter and Julie Burcell (1998), Rub\u00e9n Garc\u00eda (2013) and Erika Moranchel (2014).
