Field Work Experience

Below are highlights from my geological field work experiences at terrestrial analog sites for planetary research:

• Fossil Falls, near Little Lake, California

  Gravel dune field near Fossil Falls in Eastern Sierra Nevadas | October 2025

  
  

  Conducting a GSSI survey (top) and CMP survey (bottom) of gravel dunes in the Eastern Sierras.

  Field work at the Fossil Falls gravel dunes. Radar measurements were taken to study the internal structure of the dunes and identify cross bedding. Studying these features can help us understand the formation and migration of similar dunefields in Gale Crater, Mars. Field activities included:

  • Used pulseEKKO antenna set up to perform a common midpoint (CMP) ground pentrating radar (GPR) survey of the dunes.
  • Dug trenches to assess the topmost stratigraphy of the dunes.
  • Performed GSSI GPR measurements of the dunes at a higher frequency to resolve more detailed layering.

• Channeled Scablands, Coulee City, Washington

  Euphrata Fan Boulder Field | October 2024

  

  Collecting measurements of boulder heights and diameters.

  Geological field work at Euphrata Fan boulder field, Washington. Measuring boulders to ground truth GIS measurments and 3D products made in the lab. Analysis of these clasts will aid in computing flood magnitudes and serve as an analog to ancient megafloods on Mars. Field activities included:

  • Mapping and collecting coordinates of largest boulders
  • Measurement of boulder dimensions
  • Analysis of boulder distributions and composition across the landscape

• Additional Field Experience

  I have participated in several other field campaigns focused on planetary analog research, including:

  • Sedimentary structure analysis in paleolake environments
  • Geomorphological mapping of glacial features
  • Remote sensing ground-truthing for Mars analog terrain

  These field experiences have provided valuable context for interpreting remotely sensed data from Mars and other planetary bodies.
