  • Science Fair
    Dunes National Park and Preserve I realized I wanted to participate in science fair and investigate the effects of the burn on the ecosystem there I had participated in science fair once before in middle school and liked it so I figured I would try it again on something bigger After some discussions with the Park biologists and my mentor I started my project of studying how the wildfire affected the water quality and macroinvertebrates of Medano Creek This project kep me very busy for the next two years and I learned many many things along the way During the course of this project I had to apply for a federal permit to conduct research as well as a grant to fund part of the analysis that was done I had to learn how to travel in the backcountry collect water samples and aquatic macroinvertebrates the insects in the water and learn how to analyze the samples Between collecting samples every few weeks at my remote sites analyzing them and learning everything I could about water quality and aquatic insects it seemed like all I was ever doing was science fair and I absolutely loved every second of it The first year I presented my project at science fair I felt scared and nervous especially looking around at how many other good projects there were My first interviews were rocky I couldn t get my thoughts together and I really hated talking to people I did not know But throughout the day I learned to not worry about it so much and to just have fun telling my story sharing my research findings talking about the hard work I did and the fun I had and it became easier and easier This past year I was chosen to go to

  • Dancing Dunes
    dune Figure 1 is one of the largest dunes at Great Sand Dunes and its position has been mapped since 1996 The star dune is the prominent pyramid shaped dune located on the western side of the dunes A summary of the dune position as mapped with GPS is shown in Figure 2 The left side of Figure 2 shows the dune s location over time as a series of colored lines The earliest position is at the bottom of Figure 2 1996 when the dune summit had an elevation of 229 8 meters By 2000 the dune had moved 4 meters north and the elevation had changed to 228 7 meters The direction of movement is shown by the black arrow The trail of black arrows shows how the dune position has changed over time The net movement is shown by the thick gray arrow from 1996 to 2011 the star dune moved 45 meters north northeast On the lower right of Figure 2 is wind data collected at the nearby Indian Springs metrological station The black lines show the abundance of strong winds in the direction that they blow from The red arrow is the resultant or the direction sand would blow if all those wind vectors were added to one another Notice how it matches the migration direction of the star dune gray arrow On the upper right of Figure 2 is a graph showing the star dune height Overall the dune height is decreasing but when the migration is in an east west direction such as 2000 to 2002 and 2004 to 2005 then the elevation stays level or rises So what can we say about dune behavior The dune is moving northeast This is also true of the other dunes at Great Sand Dunes that
