The Black Creek watershed lies in the southern part of the Navajo Nation between the Defiance Plateau on the west and the Chuska Mountains on the east. The area is in the semiarid part of the Colorado Plateau on which there is about 10 inches of precipitation a year. We have two main purposes for embarking on the study. One is to determine the amount of runoff and peak flow rate generated from rainfall storm events falling on the 655 square mile watershed and the second is to provide the Navajo Nation with a method for estimating water yield and peak flow in the absence of adequate data. Two models, Watershed Modeling System (WMS) and the Hydrologic Engineering Center (HEC) Hydrological Modeling System (HMS) that have Geographic Information System (GIS) capabilities are used to generate stream hydrographs. Figure 1. Physiographic map of the Navajo Nation with the Chuska The latter show peak flow rates and total amounts of Mountain and Deance Plateau and Stream Gaging Stations.

  • Navajo Culture and Forestry Works Matthew Incha Origins and Beliefs
    Navajo Culture and Forestry Works Matthew Incha Origins and Beliefs Navajo culture provides a story of four worlds to explain their origins. The story can be told with numerous variations, but all agree on the following outline: The first world (black world) is where various spiritual beings began life and is where they were given names describing insects and animals. Altse Hastiin (first man) and Altse Asdzaa (first woman) were also created in this world. The beings were unable to live together in harmony so they passed through an opening in the east and entered the second world. Beings and animals that were in constant disagreement occupied the second world, the blue world.. First man and first woman faced tremendous hardships here, and crossed into the third world with the bluebird and coyote through an opening in the south. In the third world (yellow world) first man and first woman encountered great rivers flowing from east to west and north to south. Coyote stole water from the great rivers, which caused a great flood. To escape the rising waters the spiritual beings along with first man and first woman they climbed a reed that extended into the fourth world through an opening created by locusts. The fourth world (white world) was inhabited by beings that required the locusts to pass tests of character before the any beings from the third world could enter. The locusts passed the tests and all were allowed to enter the fourth world. In this world first man and first woman formed four sacred mountains with sacred dirt they had brought from the first world.

Box 588, Chinle, AZ 86503 Purpose Significance Significance statements express why Canyon de Chelly National Monument resources and values are important enough to merit national park unit designation. Statements of significance describe why an area is important within a global, national, regional, and systemwide context. These statements are linked to the purpose of the park unit, and are supported by data, research, and consensus. Significance statements describe the distinctive nature of the park and inform management decisions, focusing efforts on preserving and protecting the most important resources and values of the park unit. • Relationships. Located on Navajo trust land and having a resident community, Canyon de Chelly is unique among national park units. A mutual decision was made to establish the site as a national monument because the National Park Service and Navajo Tribal Council recognized the importance of Canyon de Chelly. The National Park Service, Navajo Nation, and canyon community work in conjunction to manage park resources and enable traditional and contemporary lifeways. • Cultural Continuity.

  • An Extended Winter Fog Event in Arizona's Little Colorado
    AN EXTENDED WINTER FOG EVENT IN ARIZONA’S LITTLE COLORADO RIVER VALLEY Robert Bohlin, WFO Flagstaff, AZ INTRODUCTION Extended dense fog events of three continuous days or more are rare in Northern Arizona and typically occur in the Little Colorado River Valley (LCRV). Based on Winslow airport surface observations from NCDC, extended fog events with ¼ mile visibility or lower have occurred at least 11 times in the LCRV from 1952 to present. During this same time period the month of December recorded 7 of these 11 events, more than any other month. The purpose of this WES case was to help forecasters anticipate the onset, duration, and dissipation of these extended LCRV fog events. This study examines one event which started on December 9th 2004 and ended on December 15th 2004. Prior to the fog event, a winter storm moved into northern Arizona covering the entire LCRV with 3 to 9 inches of snow. After the snowfall, a significant warm up in temperatures caused the snowfall to melt rapidly. The available moisture was trapped in the LCRV by a strong subsidence cap which prevented both vertical mixing and horizontal advection of the moist airmass under the cap. This fog event produced a significant visibility hazard (Fig. 1) for six days as an extensive area of fog eventually blanketed much of northeastern Arizona. Fig 1.

Congress, Suite #100, Tucson, Arizona 85701 This report is preliminary and has not been edited or reviewed for conformity with Geologic! Survey standards A STUDY OF REGIONAL GEOPHYSICAL DATA IN THE HOLBROOK AREA, ARIZONA An analysis of the available geophysical data in the Holbrook basin area of north central Arizona in Coconino, Navajo and Apache Counties has been made. This study has been supported by a contract with the Arizona Oil and Gas Conservation Commission, John Bannister, executive secretary, and the Four Corners Regional Commission. The primary objectives of the analysis were to determine: (1) thicknesses and lithology of sedimentary column overlying Precambrian basement; (2) structural configuration of basement surface, faults in basement and sedimentary rocks; and (3) anomalous conditions within the sedimentary rocks potentially favorable for entrapment of hydrocarbons. Location The available geological data in the Holbrook area consists of reports from the Arizona Bureau of Mines, theses, and other publications from miscellaneous sources. Approximately 20 drill holes in the area (for which lithological logs are available) penetrate Precambrian basement. Formation density logs exist for a few holes adjacent to the area of interest and in one hole within the area (appendix A). The Holbrook basin is located on the Colorado Plateau on a regionally northeast tilted homo cline of Paleozoic, Mesozoic and minor Cenozoic sedimentary strata.
