MGS MOLA Global Colorized Hillshade
This map is based on data from the Mars Orbiter Laser Altimeter (MOLA; Smith and others, 2001), an instrument on NASA’s Mars Global Surveyor (MGS) spacecraft (Albee and others, 2001). The image used for the base of this map represents more than 600 million measurements gathered between 1999 and 2001, adjusted for consistency (Neumann and others, 2001, 2003) and converted

Sagebrush-dominated ecoregions
Sagebrush-dominated ecoregions in the western United States (sagebrush cover types shown in various shades of yellow, pink, and blue-grey).
San Carlos River near Peridot, Southern Arizona - 2000
The gaging station has been removed, but the approximate position of the original camera can be established from the background mountains. The channel has shifted back to the left, eliminating the cottonwood trees present in 1964, but black willow is obvious in the foreground, cottonwood seedlings and mature trees appear throughout the view, and non-native tamarisk is

A Red-Faced Warbler in Arizona
Red-faced warblers are one of the species affected by climate change in the form of reduced snowpack in the Arizona Mountains, according to a USGS Montana Cooperative Wildlife Research Unit study.
Boundary Monument 75E, Southeastern Arizona - 1994
During the past century, the grassland has continued to become more shrubby with increases in such plants as broom snakeweed and velvet mesquite. The mesquite, occurring here near the upper limits of its range, has remained short, probably as the result of catastrophic freezes that have visited the area. Bush muhly is found beneath some of the mesquites. (Raymond M Turner

Magellan Global C3-MDIR Colorized Topographic Mosaic
The original Magellan Compressed Mosaicked Image Data Record (C3-MIDR) archive contains three times compressed mosaics of image swaths (C-BIDRs) at a resolution of 2025 m/pixel. C3-MIDRs consist of mosaics generated by computing 3x3 pixel arithmetic moving averages from the C2-MIDRs. C3-MIDRs, with their 2.025 km pixel widths, are designed to cover the planet at reasonably

Flash Floods: USGS Against the Water
A glimpse at the often dangerous task USGS employees make every year to obtain stream flow measurements from flood events.
Verde-Tangle Severe Flood 1993
This video documents two USGS employees taking a flood measurement during the most severe flood Arizona has seen in 100 years.
Santa Catalina Highway, near Tucson, Southern Arizona - 1987
This image was taken above the Santa Catalina Highway near mile 2.8 a few months after a fire burned across a south-facing slope. The saguaros are showing the effects of being scorched but are still standing. (Raymond M. Turner).

A new U.S. Geological Survey (USGS) report estimates that 15 to 20 percent of average annual recharge to aquifers occurs along the normally dry (ephemeral-flow) washes in the Sierra Vista area.
In its latest report on water use in the United States, the USGS looked at the nation's dependence on ground water. The report entitled Estimated Withdrawals from Principal Aquifers in the United States, 2000, provides details of ground-water withdrawals and use from principal aquifers in each state.

A group of federal and university scientists today announced the launch of the Western Mountain Initiative, a 5-year effort funded by the U.S. Geological Survey (USGS) to better understand ongoing changes in the mountains of the western United States.
Farmlands, wetlands, forests and deserts that composed the American landscape in the early 20th century have frequently been transformed during the past 30 years into mushrooming metropolitan areas as urbanization spreads across the country.
