These areas <br />' are generally too small, too patchy, too uneven, and too <br /> wooded to permit economical agricultural use (other than <br /> i <br />i <br /> ng of nat <br />graz <br />ve understory grasses). The hardwoods <br /> dominate along the streams with the exception of the extreme <br /> southern portion of the study area where small amounts of <br />' land have been cleared and irrigated. It should be <br /> emphasized that the hardwood vegetation type, located <br />' i <br />di <br />t <br />t <br />l <br />d <br />t t <br />th <br />th <br />l <br />ti <br /> mme <br />a <br />jacen <br />e <br />y a <br />o <br />e s <br />reams, was <br />e on <br />y vegeta <br />on <br />' type in the study area which was subirrigated. <br /> Where the third and fourth terraces are extensive <br />' enough to make irrigation feasible, they have been cleared <br /> and ditches have been constructed. In some cases, tame <br />' grasses have been seeded. There are a few orchards in the <br />' study area. They are all located on alluvial fans. It should <br /> also be noted that extensive areas of the alluvial fans <br /> together with the Mesaverde and Mancos uplands are dominated <br /> by the pinon-juniper vegetation type. <br />' The measurement of water levels in piezometers and <br /> wells completed in alluvial materials in the Ward Creek and <br />1 i <br /> Will <br />ams Creek valleys indicated that ground water was <br />' generally greater than 10 feet in depth (see Table 1 - Water <br /> Level Data - Glacial Mudflow Material).
