1 <br />`~ Grass was predominantly buffalo grass and cheat grass. Ground <br />visibility was generally very good, about 90 to 70$. At the mesa <br />edge were occasional small bushes and ponderosa pine, and <br />occasional stands of scrub oak. The canyons had a denser scrub <br />community with ponderosa pine, scrub oak, and other low shrubs. <br />The soil depth varied from very shallow at the mesa edge where <br />bedrock outcrops were often apparent, to much deeper (higher) at <br />the mesa top, creating a curved profile or "mounding" across the <br />mesa top between the eroded canyons. <br />1 SQRVrY R&SDLTS <br />The archaeological survey of the Winkler Light Aggregate Quarry <br />identified two prehistoric sites, three historic sites, and two <br />prehistoric isolated artifacts. <br />5DA1056 <br />Site 5DA1056 consists of a ground stone scatter at the head of a <br />small intermittent drainage. The site sits on the bedrock rim of <br />the small escarpment, about 2 m deep, which forms the head of the <br />intermittent drainage. The configuration of the drainage head <br />suggests a seasonal spring at this location, although no water <br />was in the drainage at the time of the site visit. The six <br />artifacts were found in a 10- by 5.5-m area. Artifact 6 is a <br />complete milling stone, which has one convex grinding surface on <br />a large cobble with minimal shaping. Two handstones, artifacts 2 <br />and 6, were on the site, each has one use surface. The remaining <br />artifacts are small fragments of milling stones, each with one <br />grinding surface. All artifacts were found on the surface. The <br />site displays no potential for additional depth. <br />' SDA1057 <br />SDA1057 is a small lithic quarry. The site has two small outcrops <br />of lithic material, which weathers into small fractured pieces. <br />The lithic material is a variety of Wall Mountain Tuff. The color <br />of the stone varies from brownish purple to a pale pink. These <br />colors are identified in the GSA Rock Color Chart as pale red {5 <br />R 6/2) to a lighter shade of pale red (10 R 6/2). This material <br />is more dense and more crystalline than the Wall Mountain Tuff at <br />the historic quarry, SDA1058, and the other outcrops along the <br />mesa edges. It has a chert-like texture which is better for <br />lithics than the other grades of Wall Mountain Tuff. No other <br />outcrops of this material were seen in the survey. Only three <br />pieces of this material at the site were identified as culturally <br />modified. Most of the material was unmodified. The site area <br />including the few artifacts, the two outcrops, and the associated <br />surface scatter of the stone is 19 by 10 meters. The site has no <br />potential for buried surface deposits. <br />16 <br /> <br />
