5RT2734 (MM8189) <br />Site Description. Site 5RT2734 is a large open chipped and groundstone scatter. The newly <br />recorded prehistoric site measures 120 m N/S x 225 m E/W. It sits on the east-facing slope of a low <br />finger ridge and on a terrace between two small, unnamed, intermittent drainages which run <br />generally east along the northern and southern site boundaries. Sediments on the ridge top and in <br />the drainage cutbanks are dry, cracked and clayey, light colored residuum possibly mixed with some <br />alluvium. Granitic lag cobbles are scattered across the site area. This area was previously plowed <br />and has been revegetated with wheatgrasses. A few low sagebrush are found within the site <br />boundary. Grazing livestock have impacted the surrounding area. <br />Artifacts recorded at the site include two <br />projectile point fragments (Figure 4), seven <br />biface fragments, one scraper, eight flake tools, <br />two cores, 81 flakes, and 10 manos. The first <br />projectile point is a small corner-notched <br />specimen manufactured from white chert that <br />fits within the Late Prehistoric Rosegate style <br />(Figure 3, right). The second projectile point <br />consists of a base and partial blade <br />manufactured from tan chert. This specimen has <br />a slightly concave base with shallow corner <br />notching and a straight-sided blade (Figure 3, <br />left). Similar projectile point styles date to mid- <br />Holocene contexts that are typically associated <br />'th Middle Archaic sites The bifaces are all <br />2 CM <br />r ? <br />r ? <br />VV <br />mid- to late-stage fragments and are Figure 4 Projectile points, 5RT2734. <br />manufactured from white, gray and pink/white <br />chert and brown and pink quartzite. The scraper is a side scraper made from gray quartzite. Four <br />flake tools are composed of white chert; four are made from brown chert. Four of the flake tools <br />are retouched on one margin and four have retouch and/or use wear on two edges. The two cores <br />are made of green quartzite and brown quartzite. The majority of the lithic flakes at the site are at <br />the tertiary reduction stage, although, some secondary flakes were also recorded. The predominant <br />material types are white and semi-translucent white chert. Flakes made from brown and pink/white <br />chert and red and gray quartzite were also found. The manos range in size from 5.5 to 12 cm in <br />length, 3.5 to 8 cm in width and 2.5 to 6 cm thick. Most are complete manos made from quartzitic <br />sandstone. One was composed of granite. Grinding on the manos ranged from light to heavy and <br />was present on two sides on about half of the assemblage. <br />Eligibility and Management Recommendations. Site 5RT2734 does not retain integrity. <br />The surface of the site has been impacted by both grazing and plowing and artifacts have been <br />redeposited. No Holocene deposition is present. Sediments are residual, primarily decomposed <br />bedrock, and have no potential to contain intact subsurface cultural deposits below the plow zone. <br />The site is flanked to the north and south by shallow drainages and no cultural material was <br />observed in any of the exposed cutbanks. MAC recommends this site not eligible for NRHP <br />inclusion because it retains no integrity and exhibits no potential to preserve buried and datable <br />cultural deposits. No further work is recommended. <br />32
