USGS EdMap Program

Mapping last summer, 2017, within the Jump off Joe Quadrangle.

Hello Geofam, I have some exciting news. As of March 8th, 2018, I was accepted to the EdMap program through USGS. This program allows students to learn the skills for geologic mapping through training with DOGAMI (The Oregon Department of Geology and Mineral Industries) as well as a designated professor at your institution over a period of one year.

Having a professional one on one field training experience is honestly a dream come true. I love being out in the field, and to be given this assignment for one year is fantastic. Although I will only physically be out in the field for a period of 7 weeks, give or take, the skills obtained throughout the year are invaluable. This program includes 149 universities with more than 935 students from geoscience departments across the Nation. Their mapping contributes to the geologic maps used for furthering research and education throughout the United States. I am so excited to be a part of this and contribute my map at the end of this year.

The region I will be geologically mapping is called Jump off Joe Mountain. This quadrangle is located along the northeastern margin of the Harney Basin about 40 miles NNE of Burns, in eastern Oregon. This opportunity came about through my advisor and field mapping professor Dr. Martin Streck, after last summer's field mapping course. This course took place within the lower southwest corner of the Jump off Joe quadrangle. Last summer's mapping experience allowed me to become familiar with the geologic units and petrography for the mapping area. Thus far, this region is primarily made up of rhyolitic tuffs, rhyolite, and andesite, with variations among each. Geologic mapping contributes to global efforts to map the geology of our earth. A vital aspect of education and research in the field of Geology.

A geological map is a specific map to show geological features. Rock units are shown by color or symbols to indicate where they are exposed at the surface. Geological maps can be superimposed over a topographic map with letter symbols to represent the geologic unit found in that region. More information is gathered through ongoing mapping efforts, and new geologic units may be defined, creating a detailed history. This is a critical element of the importance of geologic mapping. A geologic unit or stratigraphic unit is a volume of rock from an identifiable origin and relative age range defined by the distinctive and dominant, easily mapped, and recognizable mineral and chemical content, textural identity, physical characteristics, or organic characteristics that characterize it. Mapping geologic units allow for a better understanding of our earth's processes. This can provide geologic information to help reduce the damaging effects of geologic hazards such as landslides and earthquakes—what a neat way of unraveling our earth's history and improving our basic understandings of geologic resources. I am very excited to produce my piece of history and contribute to our earth's geologic understanding.

I will continue to keep you updated on my mapping progress and experience through the USGS EdMap program. The beginning of my work starts with gathering all geologic information for that region and compiling a concise record to understand better and research that area to produce a comprehensive geologic map. I will also begin planning my hiking routes, allowing me to use my field time more efficiently. I am very excited to start this process. Let the mapping begin!
