Throughout the 20th century, a significant amount of work was conducted at archaeological sites in Utah Valley dating to the Archaic, Fremont, and Late Prehistoric periods. Despite the amount of work conducted, very little has actually been reported in the past. As a result, very little has previously been known about either the prehistoric archaeology of the Provo River Delta area or the historic archaeological work that has taken place. This thesis presents a synthesis of historical work, a reanalysis of artifacts from previous excavations, and a review of extant documentation (including field notes, maps, and student reports) of several sites in the Provo River Delta, including the Hinckley Mounds, Seamons Mound, and the Bee Sites.

It was the purpose of this study to determine what aquatic plants were common to central Utah and to outline the ecological factors that control their distribution. The main emphasis throughout has been upon the more macroscopic aquatic plants. Such algae were included as was warranted by their size,, abundance and importance in the various habitats in which they grew. As this study progressed it became evident that there was a need for a broad survey-type study of the aquatic plants that would include essentially all of the wet lands of the central Utah region. The area of study closely corresponds to the boundaries of Utah County, although some collections were made outside the county, particularly to the east, in Wasatch County. The study was initiated in the spring of 1955 and field work was done during the summers of 1956, 1957, and 1959.

A survey of gastro-intestinal parasites in cattle and sheep in Utah Valley was conducted. Cattle in the valley were not seriously parasitized by helminths, whereas sheep usually had heavy helminth infections. Ten genera of helminths and 8 species of coccidia were identified in cattle in the valley, and 14 genera of helminths and 8 species of coccidia were identified in sheep. In conjunction with the survey, meteorologic studies were conducted May through September, 1909, to ascertain the effects which irrigation had upon micro-environments on grass pastures in relation to the development of free-Iiving stages of gastro-intestinal nematodes of ruminants. The effects of irrigation were such that soil moisture remained high throughout the pasture season, and moisture released from the soil to the atmosphere was redeposited as dew almost every night during the study period. Temperature and moisture conditions were conducive for development and survival of gastro-intestinal nematodes during the entire 1969 pasture season.
