Rose Springs Sloping Point

This triangular point features a slender, stemmed profile with a cross-sectional shape that transitions from flat to elliptical. The blade's curvature can range from subtly concave to entirely straight. The shoulders, which can be either pronounced or barely discernible, are positioned at an incline. The stem typically exhibits a slight outward flare, although it may also remain straight. The basal edge varies in shape, spanning from a straight line to a gently convex curve. The flaking pattern on this point is characterized by a non-uniform, random arrangement of flakes.

The dimensions of the arrowheads are characterized by the following measurements: overall length ranges from 15 to 40 mm, with a mean length typically falling between 18 and 28 mm. The stem portion measures between 4 and 8 mm in length. The blade itself exhibits a width of 8 to 20 mm, while the basal width is narrower, spanning 4 to 8 mm. In terms of thickness, the arrowheads measure between 3 and 6 mm.

This projectile is dispersed throughout the Great Basin region and extends into the northern sector of the Colorado Plateau. Its northern boundary is marked by the Snake River Plain, its eastern edge is defined by the Colorado River valley, its western limit is bounded by Death Valley and eastern California

The emergence of the bow and arrow technology in the Great Basin region marks a significant milestone in the evolution of Native American projectile points. As noted by Justice (2002), the earliest true arrow points signify a crucial transition in hunting technology. Within this context, the Corner Notch, Side Notch, and Stemmed variations of these points may be viewed as a continuum of technological development, rather than distinct, separate types. A key factor distinguishing between the Corner Notch and Side Notch types is the extent of re-sharpening, which can alter the shoulder and notch placement, ultimately maximizing the basal region. In contrast, the Stemmed variation often features a slightly expanding stem, with the degree of expansion potentially influenced by factors such as notching accidents or the size and sharpness of the notching tool.

The classification of these points has undergone refinement over time. David H. Thomas (1981) notably combined the Rose Springs and Eastgate types into a single category, dubbed the Rosegate Cluster, due to the overlap in their characteristics. This consolidation highlights the complexities of point typology and the need for nuanced understanding. The Rosegate point bears similarities to the Eastgate point, although it lacks the distinctive square barbs typically associated with the latter. Additionally, Rosegate points tend to be narrower than their Eastgate counterparts. Both types are considered extensions of the Elko Corner Notch type, adapted to accommodate the shift from dart points to arrow points. This evolutionary trajectory ultimately gave rise to the Desert series and Cottonwood points, which supplanted the earlier types (Justice, 2002).

A closer examination of these points reveals notable characteristics that underscore their significance in the context of Native American technological development. The Corner Notch, Side Notch, and Stemmed variations demonstrate a range of adaptive strategies, from re-sharpening and notch placement to stem expansion. These modifications reflect the ingenuity and resourcefulness of Native American communities as they navigated the transition to bow and arrow technology. As such, the study of these points offers valuable insights into the cultural and technological dynamics of the Great Basin region during this period, highlighting the complex interplay between innovation, adaptation, and tradition.
