Mammoth Site

By Gavin Seltz

Underground water dissolved limestone and shale
About 26,000 years ago.
The rock collapsed
A water-filled sink hole began to grow.

Young bull mammoths
Looking for an easy lunch
Drank the warm water
And the grass they did munch.

But the pond was too deep,
The bank was too slippery and steep.
The ice age mammals could not
Escape their fate: eternal sleep.

For thousands of years
Coarse sand and clay
Covered their bones,
Preserving them until the day

A bulldozer hit a tusk!
Scientists came and found the remains
Of 61 mammoths
In the South Dakota plains.

Jenna Salvat, Colorado Springs Mineralogical Society’s Earth Science scholar and former Pebble Pup, took home the top prize in Senior High Physical Science category at the 2017 Pikes Peak Regional Science Fair when she won first place on February 28, 2017. Jenna was presented her award by Dr. Rob Kolstad during the awards ceremony at Library 21C in Colorado Springs amid the cheers of her family, fellow students, and Steven Veatch, Pebble Pup Director.  Jenna also received several other awards:

  • Armed Forces Communications and Electronics Association
  • Arizona State University Walton Sustainability
  • Association for Women Geoscientists
  • Georgia and Charlie Matteson Award
  • I-SWEEP Outstanding Scientist
  • NASA Earth System Science Award
  • Northrop Grumman Excellence Award
  • US Air Force Award
  • US Navy Science Award

Jenna was one of 40 students invited to the Colorado Science and Engineering Fair, April 6-8, 2017 at Colorado State University, and she was one of only three students invited to the Intel International Science and Engineering Fair (Intel ISEF). The Intel ISEF will be May 14-19 in Los Angeles.
Jenna’s work has caught the eye of Fishbowl Films of Los Angeles, California. The movie company is planning a film about selected teens growing up in the 21st century who create scientific solutions to the most pressing issues on the planet through their participation in the largest and most prestigious high school science competition in the world, the Intel International Science and Engineering Fair. The film, by Laura Nix, plans to document the start of Jenna’s science fair to the end of her journey as a competitor at the Intel ISEF.

Jenna’s award-winning project was on crystalline silicon dioxide and the potential of the generation of voltage through its pyroelectric (charge generated when heated or cooled) and piezoelectric (charge generated in response to applied mechanical stress) properties.
According to Jenna, “The highest point in the project was watching the electrical signal feedbacks on the oscilloscope as it recorded the electrical fields being induced by mechanical stress and temperature increase.”  Jenna conducted some of her investigations at one of the laboratories at the Colorado School of Mines. Dr. Katharina Pfaff, a research assistant professor at the Colorado School of Mines, was instrumental in making arrangements for Jenna to use the QEMSCAN lab.

The most difficult part of Jenna’s science fair project was locating a facility to conduct her experiments. Jenna plans to continue her research and will need to find a research institution with an interferometer, a lock-in amplifier, and a He-Ne laser for next year. She is also in need of a large-scale autoclave or autoclave reactor with a buffer that allows for two distinct temperature gradients. Jenna said, “My plans for the future are to utilize more precise methods in relation to my experimentation and characterization for next year's portion of this project. I will begin to test a wide variety of materials that are classified as thermovoltaics. I will test these using the proper instrumentation and represent my data mathematically. I will be able to further characterize thermovoltaic materials by calculating their coefficients. I also will pursue the hydrothermal synthesis of alpha-phase silicon dioxide and will learn how to prepare silicon wafers. I plan to develop a small scale thermovoltaic transducer or electromechanical energy system that can be implemented in surface geothermal vents and features, as well as a variety of other applications. 

Jenna is in 10th grade at Coronado High School. She is also a volunteer interpretive ranger at the Florissant Fossil Beds National Monument in the summer.

Pike Peak Pebble Pup Wins Big at State Science Fair

By Steven Wade Veatch

Jenna Salvat, a ninth grade student at Coronado High School, brought home several awards from the recent Colorado Science and Engineering Fair held at the College of Natural Sciences Education and Outreach Center at Colorado State University in Fort Collins on April 9, 2016.
Her entry, “Sandstone Injectites in Fault Zone Areas: Sedimentological Characteristics Using Analog Models,” won second place in the Senior Division Earth and Space Sciences at the Colorado Science and Engineering Fair. Jenna’s work was honored by other organizations, including the Colorado Mineral Society, the Rocky Mountain Association of Geologists, and the Colorado Section of the American Institute of Professional Geologists. Jenna also received the Naval Science Award and the NASA Earth Science System Award. Her hard work has paid off in spades.

Before moving to the state finals, her project won first place in the regional Science Fair held at the University of Colorado at Colorado Springs on February 27, 2016.  Jenna will now travel with her project to the Intel International Science and Engineering Fair (ISEF) to be held in Phoenix, May 8-13, 2016. The ISEF is the leading pre-college scientific and engineering research event that is held each May.  In Phoenix more than 1500 students from 70 countries will compete for scholarships, tuition grants, internships, and other prizes.

Jenna began her work last summer with two sponsors: Christine Siddoway, a professor of geology at Colorado College and geoscience researcher Steven Wade Veatch. Jenna’s project centered on analyzing sandstone injected into Pikes Peak Granite. Jenna looked at the simulated rate of injection of liquefied sediment into igneous rock under variable densities and how that would impact the formation of sedimentary structures.

“My project helps to understand the numerous and complex sedimentary structures at exposure sites in the Pikes Peak region that were created in response to the agitation caused by fault zone earthquakes,” Jenna said.

The science fair teaches students how to explore a topic of their own interest, using real scientific inquiry, and then learn how to present their findings. Jenna’s science fair project began on a field trip to the sandstone she is investigating through the Pebble Pups, a special program for youth in the Pikes Peak region to learn about the geosciences. Since then Jenna has put in countless of hours into the project.   She would like to be a geoscientist. “I enjoy the process of science and working at the frontier of discovery,” she said.

Jenna is a member of the Pikes Peak Pebble Pups and is an Earth Science Scholar in that program. The Pebble Pup program operates under the Colorado Springs Mineralogical Society. Jenna is also a member of the Colorado Scientific Society.

Barite, which is the acceptable spelling of this mineral in the United States, but spelled “baryte” in the UK, is an interesting mineral. It is appealing to the eye and is featured in rock shops and museums. Barite is the ore of barium metal.

Barite has several practical uses. In the petroleum industry, it is crushed and used as an additive to mud that is poured into wells to support the weight of drilling tools and to flush away rock chips from the drill head and bring them to the surface for geologists to inspect. Barite’s high specific gravity also helps by increasing the pressure when drilling through high-pressure zones of rock. Barium is used in aggregates to make a strong cement. Barite is commonly ground up and used as a filler in paper, paint, cosmetics, linoleum, and other industrial products. Barite increases the brilliance of glass. Barium also used a medical application with X-rays and diagnosing certain medical conditions.

This mineral can occur in a broad range of colors. These include colorless, blue, yellow, red, and green. Black barite, which is colored by inclusions, is uncommon. Some varieties even fluoresce under ultraviolet light. Another property is that barite is mostly insoluble in all acids. It is slightly soluble in sulfuric acid.

Barite can occur with lead, silver, and antimony sulfides in hydrothermal veins ranging from medium to low temperatures. 

This piece of blue barite has small interweaving crystals 
and was collected on the plains near Hartsel Colorado USA.
