Eastgate is a Great Basin arrow point named for the Eastgate site in Churchill County, Nevada, and grouped with Rose Spring in the Rosegate series, dated to about 700–1300 CE. It is made mainly of obsidian and chert and is found across Nevada, eastern California, Utah and Oregon. The split-stem variety has a notched base.

Diagnostic traits
Small, thin arrow point with a triangular blade, long straight barbs that extend to the base line, basal notches and a narrow expanding stem with a straight base.
Identification
Eastgate has longer, squarer barbs and basal rather than corner notches compared with Rose Spring, which has a more rounded barb and corner notching; the two are often lumped as Rosegate. Desert Side-notched and Cottonwood Triangular are the later types that replace it.
Reproductions and fakes
Small obsidian arrow points are the most reproduced Great Basin artifact; genuine ones show hydration dulling and are never uniformly needle-sharp on both barbs.
