San Carlos River near Peridot, Southern Arizona - 1964
Riparian vegetation has increased to the extent of blocking the downstream view. The channel appears to have shifted to the right, and the terrace is now occupied by cottonwood, black willow, and tamarisk. (Raymond M. Turner).
Huérfano Butte, Santa Rita Experimental Range, Southern Arizona - 1941
Members of the 1930s burrowed and cholla eruptions were visible in 1941 as well as new mesquite plants that were already quite large. (Photographer unknown).
San Carlos River near Peridot, Southern Arizona - 1940
In 1940, the gaging station for the San Carlos River was on a railroad bridge south of the little town of Peridot. This downstream view from that bridge shows the gage house on the extreme left and a safety railing next to it. The channel is wide following a flood, and scattered Frémont cottonwood trees are along channel right. The dense shrubs on the low terrace on the

Huérfano Butte, Santa Rita Experimental Range, Southern Arizona - 1902
Ground repeat photography location 233 looking west at Huérfano Butte, at 1,159-meter elevation. In 1902, photographer David Griffiths’ horse-drawn buggy was clearly visible in the open grassland, and scattered desert hackberry plants were behind and on either side of the buggy. (David Griffiths).

Annex PDS Status Classification Chart
The PDS archive status (marked at upper right of each product page, see table) of geospatial data products in the Annex varies, depending on the source and date of delivery to the Annex. Most products are either PDS3 or PDS4 compliant, with the majority served as 8- or 16-bit “raw” GeoTIFFs (meaning uncompressed and untiled, see White Paper below) with detached PDS3 and

Weather forecasts and the Southwestern environment will be highlighted Wednesday afternoon, November 10, as The U.S. Geological Survey and the National Weather Service (NWS) host an open house at their facilities in the Dennis DeConcini Environment and Natural Resources Building on the University of Arizona campus.
Following the official dedication Friday morning, March 21, 1997, of the University of Arizona’s new Environment and Natural Resources Building, the public is invited to tour the facility on the campus at the northeast corner of Sixth Street and Park Avenue.
You no doubt are already aware of the March 21, 1997 dedication ceremony for the University of Arizona’s new Environmental and Natural Resources building at 520 North Park Avenue in Tucson. The building will be occupied by the U.S. Geological Survey, the U.S. Weather Service, and U of A students.
The presence of the U.S. Geological Survey in the University of Arizona’s Environment and Natural Resources Building marks the latest chapter in the USGS’s long association with the University and the study of earth sciences in Arizona.
The gasoline additive MTBE (methyl tert-butyl ether) was detected in some urban stormwater samples collected in 16 cities and metropolitan areas by the U.S. Geological Survey, but all detections of MTBE were less than the lower limit of the U.S. Environmental Protection Agency’s draft lifetime health advisory for drinking water.
About 2200 pounds of nontoxic red dye will be dumped into the Colorado River Wednesday (Mar. 27, 1996) as part of a controlled flood experiment in the Colorado River in the Grand Canyon, according to hydrologists at the U.S. Geological Survey.
Call the U.S. Geological Survey scientists listed below for information about the water science aspects of the controlled flood experiment in the Colorado River, Mar. 22-April 7, 1996. Mark Anderson is the key information scientist for the USGS on-site, and other scientists are working on-site and are available on a limited basis. Still others will be in the USGS office in Tucson throughout the ex

It’s spring and some people are busy cleaning house and rearranging the furniture.
Spring cleaning and rearranging of a different kind will take place in the Grand Canyon next week, as the Colorado River scours its bed and rearranges sandbars that have built up in the river’s winding channel.
