About 20 to 30 <br />percent of the gravel is 1/4 to 1/2 inch in diameter. There are <br />few cobbles or stone in the profile. The surface of sand and gravel <br />bars is covered with 2 to 3 percent stove and cobble. <br />This site is subject to flooding and also somewhat subject to soil <br />blowing. <br />VEGETATIOrr DESCRIPTION: <br />Vegetation on the pit site is nearly nonexistent due to the locetion <br />on a stream channel bed and the droughthy soil conditions. Annual <br />forbes are the most common occurring plants on the site with stick- <br />leaf mentzelia and russian thistle being the most dominant forbes. <br />Yellow sweet clover is present in very small amounts. Rabbitbrush <br />and wormwood are the only established shrub species. Pinyon pine <br />is present on the site only as a small number of seedling trees. <br />Grasses produce just trace amounts of forage on the site. Indian <br />ricegrass, sand dropseed and blue grams were found in small, widely <br />scattered areas. Forage production for grazing for wildlife is negli- <br />gible on this site. <br />The slopes to the east of the site are vegetated primarily with <br />pinyon nine end blue grams. Three awn grass are found in varying <br />amounts with some Scribners needlegrass and pinyon ricegrass growing <br />in protected areas of gullies and under the pinyon. Mountain maho- <br />gany and some oakbeush is found on rocky hill tops and sideslopes. <br />The slopes to the west of the nit are similar, except the slopes <br />are more gradual with more open areas of grass at the lower elevation <br />below the pinyon woodland. Blue grams is the dominant grass. Snake- <br />weed and gates is fairly abundant on the too slopes. Skunkbush sumac <br />is common in the gully bottoms. <br />The location of the pit site in Sand Gulch makes the site naturally <br />subject to flooding with little potential for vegetative production. <br />The area surrounding the gulch supports pinyon-juniper woodland and <br />
