Geology Tours and Virtual Field Trips by Dr. Sue Hirschfeld
A geologic guide has always made traveling, hiking, and exploring more interesting for me. I taught geology for 30 years at California State University, East Bay (formerly CSU, Hayward). My specialty was the Hayward fault and earthquake hazards. My passion has been making geology accessible to the non-geologist. This website contains illustrated, self-paced, self-guided tours or field guides in California and Colorado.

Oliver Kreylos' Research and Development Homepage - Augmented Reality Sandbox
UC Davis' W.M. Keck Center for Active Visualization in the Earth Sciences (KeckCAVES), together with the UC Davis Tahoe Environmental Research Center, Lawrence Hall of Science, and ECHO Lake Aquarium and Science Center, is involved in an NSF-funded project on informal science education for freshwater lake and watershed science. As part of this project, we are primarily developing 3D visualization applications to teach earth science concepts, but we also built a hands-on exhibit combining a real sandbox, and virtual topography and water created using a closed loop of a Microsoft Kinect 3D camera, powerful simulation and visualization software, and a data projector. The resulting augmented reality (AR) sandbox allows users to create topography models by shaping real sand, which is then augmented in real time by an elevation color map, topographic contour lines, and simulated water. The system teaches geographic, geologic, and hydrologic concepts such as how to read a topography map, the meaning of contour lines, watersheds, catchment areas, levees, etc.

Earth Scientist's Periodic Table
The Earth Scientist's Periodic Table of the Elements and Their Ions is a new periodic table designed to contextualize trends in geochemistry, mineralogy, aqueous chemistry, and other natural sciences. It is fundamentally different from the conventional periodic table in organizing entities by charge and consequently in showing many elements multiple times because of the multiple charges or valence states taken by those elements. These differences make the new table much more effective in showing trends and patterns in geochemistry, mineralogy, aqueous chemistry, and other natural sciences.

Jupiter Structural Layer Cake | Cakecrumbs
Our knowledge is mostly theoretical of course, but the gas giants are thought to have a core comprised mostly of rock and ice. This is surrounded by a layer liquid metallic hydrogen, and the outer layer is composed of molecular hydrogen. *cake is totally not to scale

In cake speak, this translates to a core made of mudcake, surrounded by almond butter cake, surrounded by a tinted vanilla Madeira sponge. There’s a crumb coat of vanilla buttercream underneath the fondant.

Commission: Earth Structural Layer Cake | Cakecrumbs
A little while ago, my sister approached me with an idea. She's doing an education degree, and her and her friends had to give a series of lessons on the geological sciences to a class of primary school kids. One of their lessons involved teaching the kids about the structure of the Earth. One of her friends came up with the idea of presenting a model of the Earth made out of cake. So my sister asked me if I could make a spherical cake with all the layers of the Earth inside it.

Ron Blakey, Colorado Plateau Stratigraphy and Geology and Global and Regional Paleogeography
The goals of this home page are to provide the following: 1. An introduction to my work: Geology of the Colorado Plateau and Global and Regional Paleogeography 2. An overview of the sedimentary geology on the Colorado Plateau 3. A general list of references, including NAU MS theses, to the Colorado Plateau 4. Up-to-date data on sedimentary rocks of the Colorado Plateau 5. Views of the ancient Earth: Plate tectonic and continental drift reconstructions of the Late Precambrian and Phanerozoic including detailed paleogeography of Southwestern North America.

Geologic Time: Graphical Representation of Geologic Time
The Geologic Time Spiral

A Path to the Past

Designed by Joseph Graham, William Newman, and John Stacy

The Earth is very old—4.5 billion years or more according to scientific estimates. Most of the evidence for an ancient Earth is contained in the rocks that form the Earth's crust. The rock layers themselves—like pages in a long and complicated history—record the events of the past, and buried within them are the remains of life—the plants and animals that evolved from organic structures that existed 3 billion years ago.

Also contained in rocks once molten are radioactive elements whose isotopes provide Earth with an atomic clock. Within these rocks, "parent" isotopes decay at a predictable rate to form "daughter" isotopes. By determining the relative amounts of parent and daughter isotopes, the age of these rocks can be calculated.

Thus, the scientific evidence from rock layers, from fossils, and from the ages of rocks as measured by atomic clocks attests to a very old Earth.

The National Map: Historical Topographic Map Collection
For more than 125 years, the U.S. Geological Survey (USGS) topographic maps have accurately portrayed the complex geography of the Nation. The USGS is the largest producer of printed topographic maps, and, prior to 2009, USGS topographic maps were created using traditional cartographic methods and printed using the lithographic printing process. Because historical maps are stored in a limited number of collections and are not readily available, the USGS National Geospatial Program (NGP) is converting these historical printed topographic quadrangles to an electronic format (GeoPDF). This scanning and processing effort serves the dual purpose of creating a master catalog and digital archive copies of the irreplaceable collection of topographic maps in the USGS Reston Map Library, as well as making the maps available for viewing and download from the USGS Store. The processing of this invaluable collection is well underway, with more than 141,000 GeoPDF maps of the approximate total 180,000 currently available for download. Over the next months the number of files available, in a variety of published scales, will continue to expand until all of the topographic maps created throughout the Survey's history are once again available to the public.

Beautiful Destruction: 11 Gorgeous Geological Maps of Volcanoes | Wired Science |
It's not always obvious what it is that scientists find beautiful about a graph, microscope slide, soil sample or some other aspect of their work. It just looks like numbers, blobs or dirt to the rest of us. But sometimes a scientific result or product is so visually appealing, anyone would want to hang it on their wall as art.

Geological maps are often in this category. And some of the most beautiful geological maps are of volcanoes. The colors on geological maps represent different rock units of different ages. With an active lifespan of thousands, or even hundreds of thousands of years, volcanoes produce many layers of ash and flows of lava that will end up as different colors on the map. And with the circular shape of many volcanoes and the radiating rock units, the maps can really be striking.

A Tapestry of Time and Terrain
Through computer processing and enhancement, we have brought together two existing images of the Nation's lower 48 states into a single digital tapestry. Woven into the fabric of this new map are data from previous U.S. Geological Survey (USGS) maps that depict the topography and geology of the United States. The resulting composite is the most detailed and accurate portrait of the U.S. land surface and the ages of its underlying rock formations yet displayed in the same image. The new map resembles traditional 3-D perspective drawings of landscapes with the addition of a fourth dimension, geologic time, which is shown in color. In mutually enhancing the landscape and its underlying temporal structure, this digital tapestry outlines the geologic story of continental collision and break-up, mountain-building, river erosion and deposition, ice-cap glaciation, volcanism, and other events and processes that have shaped the region over the last 2.6 billion years.

U.S. Geological Survey Photographic Library
he U.S. Geological Survey (USGS) Central Regional Library maintains a collection of over 400,000 photographs taken during geologic studies of the United States and its territories from 1868 to the present.

These images provide a visual history of the discovery, development, and sciences of the United States and its Geological Survey. Some photographs have been used in USGS publications, but most have never been published.
