Bringing Stakeholders Together to Discuss Water Issues in Wyoming

WyCEHG will host the second statewide Water Interest Group meeting this October 14, 2015.  

This community event is an opportunity for people interested in Wyoming water issues to learn about WyCEHG research, provide directions for future studies, and partner with the WyCEHG research team.  

WyCEHG promotes a multifaceted approach to water awareness.  Community outreach and feedback are crucial to this cooperative effort.  WyCEHG is looking forward to building on the work begun by WyCEHG scientists and Wyoming community leaders during the first Water Interest Group meeting, which took place on October 7, 2013.  

You can find registration details here.  For questions, please contact lizn@uwyo.edu

Ever wonder whether rock weathers?

When driving along Interstate 80 between Cheyenne and Laramie, you may have marveled at one of Wyoming's most colorful natural landmarks: Vedauwoo, a collection of plump pink granite rock hills.  Janet Dewey, a researcher in the Department of Geology and Geophysics, believes that their curious shape results in part from variable rates of chemical weathering of different rocks, and gradual erosion through rainfall, snowmelt, and temperature changes.  As she explains, "The rate at which different rocks weather governs the landscape, topographic expression, and the porosity in the rock."  Vedauwoo is one striking example of a phenomenon that shapes the intermountain west.

Since weathering affects the form and density of rocks, it also plays a major role in how water flows and where it is stored.  Weathering can change the chemical composition of rocks, as when weather leaches out elements like calcium.  When rocks and water come in contact, the chemical composition of both can change; this in turn changes the relationship between the two.  For example, if dissolving a portion of the rock changes the acidity of the water, then the rate of chemical weathering can also change.  Weathering and erosion can also include factors like slope and aspect.  One side of the mountain might be steeper, and one side might spend more time in direct sunlight.

Weathering also influences climate.  Weathering of silicate rock is "a pretty big sink" for carbon dioxide.  "Silicate minerals in the rock react with carbonic acid, consume carbon dioxide and produce weathering products that depend on the minerals present," explained Dewey.

Dewey and others on the weathering research team hope to identify what controls rates of weathering and erosion of rocks in the Laramie Range.  "Like many scientific problems, it's a scaling issue.  What we see at the micro scale is not necessarily what we see at the landscape scale."

Their study near the Laramie area includes several different techniques.  First is the micro (or very small) scale which includes column experiments to test the weathering of different kinds of rock.  Dewey and her team have build glass column reactors containing three kinds of crushed rock, including the pink granite that is iconic to Vedauwoo.  Water continuously flows through the columns and is allowed to react with the minerals in the rock.  They test the water runoff for traces of elements like calcium, iron, and phosphorus.  You can see a picture of these columns at left.

Another step involves taking samples of rock at different locations and mapping weathering profiles.  Researchers can also look at thinly-sliced rock under a petrographic microscope to analyze the structure, mineralogy, and grain size of the various rock types and how those features might influence weathering.  The group also uses techniques that will help them determine the landscape-scale erosion rates.  These data will be combined with geophysical data to create a multilayered map of the region.

After this phase, the team increases the "suite," or set of rocks in the water column study.  The researchers are currently testing three types of rock, but will increase to eight types.  They will also test faster rates of water flow, to determine if there is a predictable relationship between flow and rate of chemical weathering.

Dewey's motivation to explore weathering comes from an interest in understanding the future and a curiosity about the past.  She says, "From my perspective, one of the biggest issues confronting us in the future is going to be water quantity and quality.  We need to know as much as we can about the relationship between water and the rock it passes through.  Without that understanding it's easy for us to make mistakes."

In considering the past, she added, "If you've ever gone out on the landscape at Veedauwoo and stood there by those rocks, you think: Why do they tower four stories above me and I'm standing on flat weathered rock that seems to be made of the same material?  Why does that beautiful landscape exist - that we take pictures of, and climb on, and love to visit year round?  If we are sitting on one giant granite batholith, why isn't it the same across the landscape?  That's a cool question."

ICCE Expedition on Dinwoody Glacier

Dinwoody Glacier (photo credit: Kyle Nicholoff)

The word glacier conjures polar ice and Patagonian steppes, so you might be surprised to learn that the largest glacier in the lower forty-eight states is right here in Wyoming, in the Wind River Basin Mountain Range: Gannet Glacier, on the east and north slopes of Gannet Peak.   

The unique composition of glaciers offers infinite opportunities for research, especially in hydrology and earth science.  This summer, Central Wyoming College (CWC) instructor, Jacki Klancher, took student researchers up to Wind River’s Dinwoody Glacier on the second annual Interdisciplinary Climate Change Expedition (ICCE), an eleven-day investigative adventure.  She was accompanied by Wyoming EPSCoR’s own Dr. Sarah Konrad, as well as archaeologist and CWC professor Todd Guenther. 

Outdoor Education students, led by instructor Darren Wells, provided valuable assistance comprised the ICCE Glacier team. They worked on projects both on and off the ice and worked in concert with the entire team to transport all of the equipment up and down the mountain.  As Klancher said, “It’s really a testament to the team’s skills that we all got up there, completed all of our research, gathered all of our data, and got everyone back down to the parking lot without any incident.  That’s got to be a fundamental consideration – how do you keep students safe.” 

One group of students focused on black carbon, dark particulate matter sometimes found on glacial ice.  Black carbon is related to industrial pollution and can increase snow temperature and accelerate snowmelt.  Students collected snow samples to test for the presence of black carbon and establish a baseline level that can be used to compare data from this coming year.  The team also hopes to use isotopic measurements which can allow scientists to trace the black carbon to its source.

Dinwoody Glacier is a popular backpacking and hiking site, and students wanted to test to see if human waste material had contaminated Dinwoody’s streams and surface waters.  Testing for E.coli on the mountaintop was a challenge, but two archaeology students found a creative solution: a chicken-egg incubator from Ace Hardware, small enough to carry up the mountain and perfect for housing E.coli cultures.  Next year, the team plans to return with laboratory-grade testing equipment, to expand on their research.  Student researchers also collected water and ice samples to test for temperature and acidity, and surveyed aquatic macroinvertebrate populations.

Guenther's archaeology team made several exciting discoveries on the mountaintop, including a buffalo jump at nearly 11,000 feet - the highest documented jump site in the Central Rockies.  The archaeology team also found what appear to be two Paleoindian camp sites just below the glacial moraine, showing that people were living immediately under the ice some eight to ten thousand years ago.  Researchers found what appear to be several stone cairns and a large store of stone tools.  They hope to return next year to continue their investigation of the site, and are excited to learn more about early human life at high altitude.  

The ICCE expedition also created several maps of the terrain.  Geospatial data collection using global positioning systems (GPS) and maps created using Geographic Information Systems (GIS)- is a significant component of the student research.   Students use GPS to translate data into visuals that they can then use to present their research.  In the future, these visual aids will be an essential part of journal articles and conference presentations will be essential; CWC’s students have a strong head start. 

Guenther pointed out that students are already reaping professional rewards: “We are hired by the BLM and other organizations to complete archaeological projects for them, data collection using professional grade GPS units and professional maps created using ArcGIS software– students who come out of this program are trained not only in archaeology but also GIS and that opens a number of doors for them, so they can take advantage of future opportunities.”

Next year, the team hopes to collaborate with UW’s Dr. Paul Johnson on collecting and analyzing surface water samples to test again for E. coli  Team leaders also hope to collect seismic data on the glacier.

Most of the focus, however, will remain on the students: “We hope to keep expanding, both to enhance the quality of the student experience and the quality of our data.”

The University of Wyoming is Making Connections with Community Colleges and Utilizing the State’s Resources

Dr. Andrew Parsekian, a professor at the University of Wyoming, researches groundwater processes using non-invasive geophysical methods.  Having taught at the University of Wyoming for a year and a half, Dr. Parsekian brings valuable knowledge to the Geology & Geophysics Department as well as the Department of Civil & Architectural Engineering. 

This summer, Dr. Parsekian teamed up with the Northern Wyoming Community College District at Spear-O-Wigwam near Sheridan, Wyoming for a one-week course. The course was entitled Field Based Environmental Science: Examining Global Problems through a Local Lens.  More specifically, the course was designed to engage students in the scientific inquiry of environmental problems while gaining experience in field techniques.  Dr. Parsekian, Dave Munsick of Sheridan College and Scott Hardon of Gillette High School taught the class, along with the aid of Trudy Munsick, the Dean of Outdoor Education at the Northern Wyoming Community College District.  The course contained eleven early career college bound students from across the state of Wyoming.  The students spent an average of 13-14 hours a day in the field camp and received three college credit hours.  At the end of the week, the students wrote a paper, presented the results of their research, and had a comprehensive exam.  

Spear-O-Wigwam is a fascinating part of Wyoming’s history; in 1923 Wyoming State Senator, Willis M. Spear, founded it as a dude ranch.  The acclaimed writer, Ernest Hemingway, used Spear-O-Wigwam as one of his writing workshops in the 1920’s.  Hemingway was quoted saying that Wyoming and Africa were his two favorite places to be.  As an ode to Mr. Hemingway, there is a cabin at Spear-O-Wigwam named after him.  The Northern Wyoming Community College District purchased Spear-O-Wigwam in 2011 in order to enhance their academic programs.  Located in the Bighorn National Forest, Spear-O-Wigwam offers many educational outdoor opportunities. 

Many high school students are not exposed to hypothesis driven science due to lack of time and resources.  Hypothesis driven science uses deductive reasoning wherein an idea or hypothesis is proposed and then tested.  Dr. Parsekian’s course introduced hypothesis driven science to the students who participated.  Wyoming’s resources are plentiful and this course took advantage of Spear-O-Wigwam to conduct their hypothesis driven science research.   

As the only University in the State of Wyoming, it is important to make connections with the community colleges and share each other’s resources since across the state; Wyoming has a lot to offer.  Dr. Parsekian will run a similar course next year with a different science question to be researched and answered by students at the Northern Wyoming Community College District.  For more information regarding registration or community events, visit www.spearowigwam.com
