Their soils are generally residU'1l frcm sh8.le and <br /> <br />of clay texture, although there are small lenses of gravelly soil <br /> <br />and some of fine sandy soil. All the subsoil is an open porous <br /> <br />gravel. <br /> <br />Some alkali spots h'1ve developed. <br /> <br />~.~ <br />' ,"~':t. <br />, .,.'1'.~' <br />;.~ <br /> <br />The greater part rf Florida Mesa is red sandy to red clay <br /> <br />loam of goodquali ty 31ld greBt depth. Toward the edges of the mesa <br /> <br />on the east, south, 31ld west, the soil is thinner and the points be- <br /> <br />tween the numerous .deep, short gulches of the south are non-arable. <br /> <br />Toward the north the soil bec0mes thinner and is in places residual <br /> <br />fr0m the underlying shale and sandstone. A subsoil of only fairly <br /> <br />open gravel is present except under the residual soils, and the <br /> <br />latter are higher in salts. <br /> <br />Land Classification <br /> <br />Bureau of Reclamation personn'el engaged on Cclor'}do Basin <br /> <br />Investigations under Section 15 of the Boulder Canyon Project Act, <br /> <br />surveyed and classified all the land on the project. The work under <br /> <br />the immediate directirn of H. F, Bahmeier, Associate Engineer, was <br /> <br />done in 1933. <br /> <br />9 <br />
