Getting started with Structure from Motion (SfM) photogrammetry
Beth Pratt-Sitaula, EarthScope
Structure from Motion (SfM) photogrammetry method uses overlapping images to create a 3D point cloud of an object or landscape. It can be applied to everything from fault scarps to landslides to topography. This ...

Sandy Hollow Virtual Field Geology Exercise
Andrew Laskowski, Montana State University-Bozeman
This is a Google Earth based virtual field exercise focused on Sandy Hollow, near Block Mountain and McCartney Mountain in southwest Montana. This is a classic field locality in the Montana portion of the Sevier ...

Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
Research-grade Global Positioning Systems (GPS) allow students to deduce that Earth's crust is changing shape in measurable ways. From data gathered by EarthScope's Plate Boundary Observatory, students discover that the Pacific Northwest of the United States and coastal British Columbia — the Cascadia region - are geologically active: tectonic plates move and collide; they shift and buckle; continental crust deforms; regions warp; rocks crumple, bend, and will break.

Measuring the Inclination and Declination of the Earth's magnetic field with a smartphone
Avradip Ghosh, University of Houston-University Park
The poles of the Earth's magnetic field are not precisely aligned with the geographic north and south poles and, in fact, vary continuously. This activity introduces to students the Earth's magnetic ...

Measuring Ground Motion with GPS: How GPS Works
Shelley E Olds, EarthScope Consortium
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.

Karst Hydrogeology: A virtual field introduction using Google Earth and GIS
Rachel Bosch, Northern Kentucky University
Students will have the opportunity to select and virtually explore the hydrogeology and geomorphology of a karst landscape using Google Earth, lidar data-sourced DEM(s) and geologic maps, and GIS software (QGIS) ...

Converging Tectonic Plates Demonstration
Shelley E Olds, EarthScope Consortium
During this demo, participants use springs and a map of the Pacific Northwest with GPS vectors to investigate the stresses and surface expression of subduction zones, specifically the Juan de Fuca plate diving beneath the North American plate.

Poster Project for an Introductory Physical Geology Course
Eileen Herrstrom, University of Illinois at Urbana-Champaign
This page details a term project that replaced the comprehensive final exam in an introductory physical geology course. For the project, each student prepares a poster showing analysis of geological data using a ...

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
This lesson teaches middle and high school students to understand the architecture of GPS—from satellites to research quality stations on the ground. This is done with physical models and a presentation. Then students learn to interpret data for the station's position through time ("time series plots"). Students represent time series data as velocity vectors and add the vectors to create a total horizontal velocity vector. They apply their skills to discover that the Mid-Atlantic Ridge is rifting Iceland. They cement and expand their understanding of GPS data with an abstraction using cars and maps. Finally, they explore GPS vectors in the context of global plate tectonics.

Reconnaissance stratigraphy and mapping of the Frying Pan Gulch, MT
Sinan Akciz, California State University-Fullerton
Students are required to create a reconnaissance geologic map and report for a small area (approximately 0.5 sq. mile) Frying Pan Gulch just NW of Dillon, Montana. This project is designed to make students familiar ...
