Revisiting Lava Flow Simple Models
Simple models relating the final dimensions of a lava flow to eruption parameters an lava rheology were used extensively in the 1980's but have fallen out of use in the terrestrial vocanology community. However, in the planetary volcanology community these models have had a resurgence of utilization, especially in response to the availability of high resolution topographic...
Conferences
International Planetary Caves Conference
Planetary Caves
As USGS scientist and planetary cave enthusiast, Glen Cushing, points out, "Caves are important to the future of planetary exploration because they are believed to provide shelter from a range of harsh surface conditions, maintaining near-pristine surfaces and relatively stable microclimates." See links on this page to explore further.

Streamflow and sediment data collected to determine the effects of a controlled flood in March and April 1996 on the Colorado River between Lees Ferry and Diamond Creek, Arizona
An 8-day period of planned release of water at 1,275 cubic meters per second from Glen Canyon Dam in March and April 1996 provided an opportunity to collect data on river stage, streamflow, water chemistry, and sediment transport at discharges above powerplant releases. The U.S. Geological Survey collected data at five streamflow-gaging stations...

The Colorado River in Grand Canyon: how fast does it flow?
Opening the jet tubes at Glen Canyon Dam on March 26, 1996, released from Lake Powell a controlled flood of water that traveled down the Colorado River in Grand Canyon. How fast did the water move? How long did it take for water to reach a particular point along the river? The answers to these questions are important because the speed of river...

Geochemical analyses of ground-water ages, recharge rates, and hydraulic conductivity of the N aquifer, Black Mesa area, Arizona
The Navajo Nation and Hopi Tribe of the Black Mesa area, Arizona, depend on ground water from the N aquifer to meet most tribal and industrial needs. Increasing use of this aquifer is creating concerns about possible adverse effects of increased ground-water withdrawals on the water resources of the region. A thorough understanding of the N...

When the blue-green waters turn red: Historical flooding in Havasu Creek, Arizona
Havasu Creek, the second largest tributary of the Colorado River in Grand Canyon National Park, attracts numerous visitors each year owing to its spectacular scenery. Perennial streamflow seldom exceeds 2 cubic meters per second (m3/s), but supports important stands of riparian vegetation, forms unique travertine pools, and spills over spectacular...

An accounting system for water and consumptive use along the Colorado River, Hoover Dam to Mexico
An accounting system for estimating and distributing consumptive use of water by vegetation to water users was developed for the Colorado River to meet the requirements of a U.S. Supreme Court decree and used with data from calendar year 1984. The system is based on a water-budget method to estimate total consumptive use by vegetation which is...

Sand deposition in the Colorado River in the Grand Canyon from flooding of the Little Colorado River
Methods for computing the volume of sand deposited in the Colorado River in Grand Canyon National Park by floods in major tributaries and for determining redistribution of that sand by main-channel flows are required for successful management of sand-dependent riparian resources. We have derived flow, sediment transport, and bed evolution models...

Sonoran Desert Wildflowers and Invasive Species
Ecosystems are changing at a rapid pace. It can be difficult to determine if a landscape is in need of restoration. In this photo of the spring wildflower bloom in the Sonoran desert, an invasive annual grass, Bromus rubens (red brome), is pervasive. Land managers have to make decisions about when, where, and how to intervene in a system. Does this grass pose a threat to

Saguaro National Park, East Unit, Southern Arizona - ca. 1935
This camera station is located on a hill within the newly established Saguaro National Monument near Tucson. The view is northeast toward Agua Caliente Hill and looks down a gentle incline that drains into Tanque Verde Creek. The saguaro stand pictured here is a particularly memorable one because of the many large individuals and absence of small ones. It is an example of

Golden eagles in the Mojave Desert travel farther, to different areas, and at different times of the year than previously understood, according to research by the U.S. Geological Survey and partners from other federal agencies, academia and the private sector.
While the earth contains enough potash to meet the increased global demand for crop production and U.S. supplies are likely secure, some regions lack potash deposits needed for optimal food crop yields. According to a recent USGS global assessment of potash resources, the costs of importing potash long distances can limit its use and imports are subject to supply disruptions.
A new U.S. Geological Survey study shows how plants’ vulnerability to drought varies across the landscape; factors such as plant structure and soil type where the plant is growing can either make them more vulnerable or protect them from declines.
