Flynn Creek crater is a 3.8 km diameter, 360-million-year-old impact structure located in north central Tennessee, and is an invaluable terrestrial analog for the study of impact cratering dynamics. The Flynn Creek Crater Sample Collection consists of over two thousand boxes of drill core from 18 drill holes in the crater’s central uplift, floor, and rim. Impact-induced hydrothermal systems are of considerable scientific interest because they may have played a significant role in the origin and evolution of life on early Earth and produced temporary near-surface habitable environments on Mars. Between 1967 and 1979, USGS scientist Dr. David Roddy conducted a drilling program at Flynn Creek crater. The drilling...
Photogrammetry techniques to quantify fine-scale topography of cinder ripples were applied to a small region of interest in Sunset Crater National Monument, Arizona.
Our goal for this work is to place better constraints on aeolian atmospheric-surface interactions through long-term monitoring of an active, bi-modal dune field located near Grand Falls, Arizona. This dune field has been monitored since 2013 by the USGS, and data from each collection year are released as USGS Data Release products. Data described here is the imagery component (individual time-stamp images of an active ripple field) of the Imagery, Photogrammetry and Meteorological Data from December 2022 to April 2023, Grand Falls Dune Field, Arizona USGS Data Release. Our instruments are set up near an active ripple field in the Grand Falls Dune Field. The instrument array includes a meteorological weather station...

Metadata on this main landing page applies to all DTMs listed under Child Items, apart from USGS-made DTMs [HRSC DTM_75 (centered at -28.8N, 78.6E)_USGS and CTM DTM over "Crater L" (centered at -23.1N, 74.3E)_USGS]. Metadata associated with USGS-made DTMs are located with DTM files under their respective Child Item.
Photogrammetry techniques to quantify fine-scale topography of sand ripples with a bi-modal grain size distribution were applied to a small region of interest at Grand Falls dune field, Arizona.
The purpose of the data collection was to monitor the microclimate in the “Bonito Flow” Ice Cave located in Sunset Crater National Monument. This cave is considered a sacred spot for some southwestern tribes as it was a historical source for ice. The main purpose of the climate monitoring was to determine if the cave is still an active ice cave, i.e., a cave that contains perennial ice. The data acquired consists of temperatures, humidity, and pressures throughout the cave structure and also includes temperatures and humidity measured outside of the cave, near the entrance. Sensors were distributed throughout the cave but focus on a large ice puddle that forms on the cave floor during the winter months. Cave floors...

Grand Falls dune field (GFDF) is located on the Navajo Nation, ~70 km NE of Flagstaff, AZ. This active dune field displays a range of morphologies, including barchans, smaller dunes, and ripples, and is bimodal in composition. The felsic component is likely derived from the Little Colorado River, and the mafic component (basaltic grains) is locally sourced from nearby cinder cones [1]. GFDF is an excellent analog site for both active dunes on Mars and other planetary bodies that have dune-like features (e.g., Venus and Titan). We have set up a meteorological station within the dune field that records temperature, barometric pressure, relative humidity, wind direction, wind speed, solar radiation, and precipitation...
Meteor Crater, located in northern Arizona, is one of the best preserved and easily accessible impact sites on Earth. Scientific investigations of this crater have led to improvements in our understanding of impact mechanics, cratering dynamics, and ejecta distribution [e.g., 1-5]. In addition, this site has a rich history as a terrestrial analog that has been used for training astronauts, scientists, and engineers [e.g., 6-8]. In the 1970s Dr. David Roddy conducted a rotary drilling campaign at Meteor Crater, along the rim, flanks, and surrounding ejecta blanket [9]. This work resulted in 2,500 m of drill cuttings from 161 drill holes. The original samples were placed in sandwich-sized plastic bags with slips of...

The vadose zone (unsaturated zone) in a soil is of particular interest because it is broadly applicable to desert soils, which are seldom saturated and usually dry. In the absence of strong geothermal heating, the near-surface soil temperature profile is expected to exhibit maximum variation (for a given diurnal period) at the surface, with the diurnal variations becoming successively damped with depth. The temperature at a given depth is the result of diffusive heat transport vertically within the soil column. Water vapor also is expected to be transported via diffusion through the soil column [1]. We have selected a small cinder field in Sunset Crater National Monument, Arizona (SUCR) and deployed temperature...

A High Resolution Stereo Camera (HRSC) digital terrain model (DTM) was created for quantitative measurements of sinuous ridges on the surface of Mars using HRSC image h6430_000.
We created this guide to introduce the user to the San Francisco Volcanic Field as a terrestrial analog site for planetary volcanic processes. For decades, the San Francisco Volcanic Field has been used to teach scientists to recognize the products of common types of volcanic eruptions and associated volcanic features. The volcanic processes and products observed in this volcanic field are like those observed on lunar and Martian surfaces. As a result, this region has been a favored location for training National Aeronautics and Space Administration astronauts and engineers since the Apollo missions.
The Mars Global Digital Dune Database provides a comprehensive and quantitative view of the geographic distribution of dune fields from 65° N to 65° S latitude. The database encompasses ~ 550 dune fields, covering ~ 70,000 km2, with an estimated total volume between 3,600 km3 and 13,400 km3. Over 2300 selected Thermal Emission Imaging System (THEMIS) infrared (IR), THEMIS visible (VIS) and Mars Orbiter Camera Narrow Angle (MOC NA) images were used to build the database and are included in the ArcMap and ArcReader versions of the database. An initial data set of THEMIS band 9 spectral range images covering orbits 816-9601 (spanning 02/2002 - 02/2004 and Ls = 0.085º-358.531º) and comprising more than 30,000 images...
