Vegetation at CHCU was mapped and classified by a combination of existing plot data and data collected for the purposes of this project, several field visits and photo interpretation. The protocols and standards used are those for medium sized parks and are described in the NPS/CSS program documents (TNC and ESRI 1994a) (section 5.1). BOR was contracted by the Southern Colorado Plateau Network in 2005 to map approximately 18,800 ha (~46,500 acres) of Chaco Culture National Historical Park and environs. The vegetation map is a 1:24000 scale product.To effectively classify and map the wide range of vegetation at CHCU required a multi-year approach and consisted of several linked phases: (1) vegetation classification...
Vegetation at NAVA was mapped and classified by a combination of field plot data collected in 2005 and photo interpretation from 1:12,000 scale color aerial photograghs acquired in June of 2004. The protocols and standards used are those for small parks and are described in the NPS/BRD program documents (National Mapping Program Field Methods for Vegetation Mapping (1994a) for small parks (section 5.1). BOR was contracted by the Southern Colorado Plateau Network in 2005 to map approximately 2,500 acres (~ 1000 ha) of Navajo National Monument and environs.Vegetation mapping for NAVA encompassed both the executive boundary of NAVA, and a 0.5 km environ buffer. Field reconnaissance focused most on the area within the...
Nine BlazeVideo cameras have been set up surrounding an active ripple field and meteorological station within Grand Falls dune field, Arizona. Images are taken at a set time to record sand movement. Data presented here span from April 22, 2021 to December 7, 2021.

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...
Development of a high-resolution digital elevation model (DEM) of the pre-Glen Canyon Dam topography in Glen Canyon National Recreation Area, Utah and Arizona was initiated to assist the U.S. Geological Survey (USGS) in its Lake Powell coring program in the fall of 2018 (https://www.usgs.gov/centers/ut-water/science/lake-powell-coring). Topographic surveys of Glen Canyon were commissioned by the Bureau of Reclamation during the planning stages for Lake Powell as part of the Colorado River Storage Project (S. 500, 1956). The Colorado River arm was surveyed by Alster and Associates, Inc. in 1958 and 1959 at a contour interval of 10-feet from the river surface at the future dam site through where the 3,750-foot contour...

A meteorological station equipped with a rain gauge, atmospheric pressure sensor, temperature and relative humidity sensor, soil moisture sensor, and an anemometer (measuring wind speed, gust speed, and direction) was deployed at Grand Falls dune field, Arizona. This dataset has been collecting data every 15 minutes with the goal to provide context for ripple and dune migration at an active dune field site.

Apollo Applications Program Field Test 5 was held March 14-18, 1966, in the Hopi Buttes area, Arizona. The objectives of the test were to 1) evaluate techniques of field checking a moderately complex photogeologic map--techniques potentially useful for lunar geologic exploration; 2) test the feasibility of using a vehicle mounted magnetometer and applying the magnetometer results to real time geologic mapping and interpretation; and 3) evaluate the use of a petrographic microscope as a possible analytical tool for lunar exploration. The test results indicated that for real-time mapping at a station remote from the fieldwork, persons working in the field and at the remote station must be trained as a team, and that...
A shirtsleeve test of geologic reconnaissance methods applicable to lunar surface exploration was conducted using astronauts as subjects. The task analysis objective was to determine the efficiency of a 2-man traverse. A table summarizes the full-day traverse, and a process chart (time line) is included in the report. It was concluded that two astronauts can complement each other's work with little or no time lost by one waiting for the other.
