Many Earth scientists use geographic information science/systems (GIS) in their work. This video has two goals: 1) emphasize that the creation and admiration of MAPS is a huge part of being a geologist. Many of us are fortunate to have the opportunity to create maps of our own – I hope you see some of my passion for this aspect of our science, and 2) give a simple tutorial for how to gather and manipulate digital elevation model (DEM) data to create a crisp hillshade in Esri’s ArcGIS Pro. I hope you find this video interesting.

A simple one-take video from the High Andes of Chile describing what it means to create a geologic map. Field geologists go out into the mountains and do their best to determine the spatial relationship between different lithologies with different ages. Sometimes geologic structures like faults and folds are required to explain the observed distribution of rocks at Earth’s surface. A finished geologic map provides much valuable information on the local to regional geologic history of an area.

A geologic map is a graphical representation of the distribution of different types of rock and sediment at the Earth's surface. This video shows the easy yet under appreciated workflow to access and download geologic maps that can be loaded into Google Earth Pro. As I show, this is an enlightening and fun way to visualize geology after a hike or walk through nature. I hope you find something in this video interesting or valuable.

In this video, I give an informal overview of most the gear I bring on expeditions to the high Andes for geologic field work. This will be helpful if you are an undergraduate approaching field camp, or even simply your first field experience. Of course, you DO NOT need all the things I show in this video. I highlight the unfortunate fact that getting durable and protective gear can be very expensive (in some cases preventing people from being able to pursue their passion). But hopefully it is also made clear that you don’t need the NICEST stuff out there. I get by with lots of old and second-hand materials in some of the most rugged environments on Earth. Please let me know if you have any questions – and thank you for accepting my casual delivery. A lot on my mind prior to an expedition! Let me know if you have questions about gear, including if you face barriers to access adequate field gear.

University of Arizona Geoscience PhD students Caden Howlett and Chance Ronemus recently completed a ten-week field season in the south-central Andes of South America (31-36S). This video records an average day in the life of a geologist. We sample rock for thermochronology, give some tips on conducting field work abroad, and reveal our normal base camp operations. Please reach out with any geology-related questions and I hope you enjoy the video. Our work is part of an interdisciplinary effort to understand the geologic evolution of the Andean mountain belt (TANGO; the “Trans ANdean Great Orogeny”). Funding for this research is provided by the Frontier Research in Earth Sciences (FRES) program and the National Science Foundation (NSF).

What happens to “plate tectonics” as we know it on an enormous exoplanet? Is it possible for half a planet to have active tectonics? Why is the moon covered in craters and Earth subduction zones and mountain belts? In this video, I discuss a recent short perspectives paper from Stern et al. (2023). They broadly discuss the definition of tectonics and how it may vary across terrestrial bodies. I share some of the aspects that I found most interesting and how it relates to what I think about as a PhD student in geology. It is essential that we continue to investigate plate tectonics on Earth in order to understand how planets evolve and the feedbacks/links between mountain building, landscape evolution, climate, and the origin and evolution of life.
