This book on the "History and Economic Resources of the Navajo Nation" is the result of a joint effort by two geologists, Dale Nations and Henry Haven, both of whom have studied the geology, and worked on the Navajo and Hopi Lands for many years.
Dale is a Registered Professional Geologist and former University Professor who has devoted many of his professional years to research on the rocks on Navajo and Hopi lands. He and co-author Henry Haven published their work as the U.S.G.S. Professional Paper No. 1625 in 2000 and have written a previous book on "Traditional Navajo Stories and the Science of Geology" in 2023. For this book, they have summarized the relevant information on coal, oil and gas, groundwater, uranium, helium, hydrogen, and industrial minerals occurrence on Navajo and Hopi lands. They also review Navajo cultural activities of economic significance, such as weaving, silversmithing, pottery, forestry, and livestock management.
Henry is a full-blooded Navajo who grew up speaking the Navajo language and experiencing the Navajo culture. After earning Bachelor's and Master of Science degrees in geology, he worked several years as a Petroleum Geologist in the Four Corners area and Texas, then returned to Dineh Bikeyah to study the coal resources of Black Mesa. He worked for the Navajo Nation Environmental Agency from 2000 to 2024. Henry contributes to the Navajo people's belief in the wise use of water, land, and resources.
Both authors have an appreciation for the economic significance of the natural resources of Navajo and Hopi lands and have encouraged their wise utilization. This book summarizes the natural resources of the Navajo and Hopi lands, and their relationships to Native American cultures. The border of the front cover is a design from a traditional Navajo rug that was woven by Henry's grandmother Hazel Cornfield in the early 1970s.

Dale
Nations
Dale Nations, PhD, P.G. is a retired university Professor who taught geology and paleontology at Northern Arizona University and conducted geologic research on the Navajo and Hopi lands for 31 years. He and co-author Henry Haven published their work on the coal resources of Black Mesa as the U.S. Geological Survey Professional Paper 1625, and a Kendall/Hunt book on the Navajo traditional stories and the science of geology. Both are experts on the geology of the area including the occurrence of oil and gas and other natural resources of Navajo lands.
Henry Haven
Henry Haven, a full-blood Navajo, grew up on the Navajo Reservation speaking the Navajo language and experiencing first-hand, the Navajo culture. Henry’s traditional clans are, “One who Walks Around You” Clan, born for the “Bitter Water” Clan, his maternal grandfather is the “Red Running into the Water” Clan, and his paternal grandfather is of the “Coyote Pass” Clan.
Henry received his BS degree in Geology from Fort Lewis College in 1976 and an MS degree in Geology from Northern Arizona University in 1997. Henry has since had a successful career as an oil company petroleum geologist, Navajo Nation Minerals Department geologist, and Environmental Geologist for the Navajo Nation Environmental Protection Agency (NNEPA). His work as a petroleum geologist included interpreting electric logs on open boreholes for oil and gas companies in Texas and in the Four Corners area. Henry has retired and is now contracting with the Navajo Environmental Protection Agency as an Environmental Geologist, which includes remediation of hydrocarbon contaminated groundwater sites on Navajo land.
Henry was co-author of a U.S. Geological Survey Professional Paper 1625-H, in 2000 titled, “Summary of Cretaceous Stratigraphy and Coal Distribution, Black Mesa Basin, Arizona, which included his Master’s thesis at Northern Arizona University in 1997. He also co-authored a book titled, “Navajo Traditional Stories and the Science of Geology “in 2023 with Dale Nations, geologist, and Max Goldtooth, a Navajo Medicine Man.
In addition to these accomplishments, Henry is currently co-authoring with Dale Nations another book titled “History and Economic Resources of the Navajo Nation” (in press). This new work aims to provide a comprehensive overview of the Navajo Nation's history and economic development, with a particular focus on the land and water resources that are vital to the community's livelihood and heritage.
