City of Rocks Annotated Bibliography

Miller, David. M., & Armstrong, Richard. L., & Bedford, David. R., & Davis, Marsha. (2008). Geologic Map and Digital Data Base of the Almo Quadrangle and City of Rocks National Reserve, Cassia County, Idaho. USGS. Retrieved from USGS database.

This is a geological map that states what the geology and terrain of the area is like in City of Rocks, Idaho. It lists the layers of the rock’s history in order, and the types of rocks that are found in the area. It mostly consists of granite and granite gneiss. It shows that there are a lot of alluvial fan deposits and landslides that occur. I will use the information about the types of rocks and the layers of rocks to learn more about and better understand the history of the park and the geological features.

Thornberry, Ehrlich. T. 2010. City of Rocks National Reserve: geologic resources inventory report. Natural Resource Report NPS/NRPC/GRD/NRR—2010/191. National Park Service, Ft. Collins, Colorado, Retrieved from City of Rocks National Reserve Geologic Resources Inventory Report.

This is a report about the City of Rocks from the City of Rocks National Reserve Geologic Resources Inventory Report. It discusses geologic issues, features and processes, map properties, and geologic history. The park is made of  molten and metamorphosed rock, the oldest are more than 2.5 billion years old. This rock sits against the Almo pluton. These have been weathered to form how the City of Rocks looks today. This report also explains how part of the California Trail led through the rock formation. There are roads, trails, and graffiti left from the passage. This report is very helpful and has a lot of information about weathering, rock formations, and history about the park.

Dorworth, Dick. (2015). The City Of Rocks, Sun Valley Magazine, 102-106

This is an article about the City of Rocks. It is about the cultural and tourist impact on the park. It states that there is evidence that people have been in the City of Rocks for 9.000 years. The Shoshone Bannock tribes used to live near it and the westward expansion also had an affect on the park’s geologic history. The granite pluton is some of the oldest exposed rock found on the Earth, it can date back to 2.5 billion years. I will use this to better understand the geological history of the park and the structural composition of the minerals and rocks found.

Morris, Lesley. R. (2008). Combing Environmental History and Soil Phytolith Analysis At The City Of Rocks National Reserve: Developing New Methods in Historical Ecology. Logan, Utah: ProQuest LLC.

This is a book about the environmental and geological history though soil phytolith analysis, and detailed research at the City of Rocks. There is information about fires and charcoal layers at the park. There is a lot of information of phytoliths and how they can show the history of the environment. There are phytolith layers listed and they explain the history of the park. There is also history about the Native American Tribes and European settlers and explorers and their impact on the geologic site.

Miller, David. M., Bedford, David. R. (1999). Pluton Intrusion Styles, Roof Subsidence and Stoping, and Timing of Extensional Shear Zones in the City of Rocks National Reserve, Albion Mountains, Southern Idaho. AAPG Datapages Archives. Retrieved February 25, 2018, from http://archives.datapages.com/data/uga/data/070/070001/11_ugs700011.htm

This is about the rock and geological formations at the City of Rocks. It describes the formation and intrusion of the Almo pluton. It is mostly composed of granite. There is stoping and roof subsidence located at the park. There is information about the timing of shear zones and what causes the plutons and rock to intrude from within the Earth. This information will be very helpful in understanding the Almo pluton and how the rocks formations were formed.
