Many researchers utilize shallow ground temperature measurements in their studies; usually at one meter depth on a sparse, irregularly spaced sampling interval. However, one meter depth can be invasive to fragile environments and take substantial time. We propose the use of temperature probes 25 centimeter in length on a set grid with high density spacing (e.g., 72 x 72 meter with 3 x 3 meter spacing). The high density sampling interval on a set grid is superior because it allows for the development of spatial correlation relationships, and because the uncertainty of the measured temperatures decreases proportional to the square root of the total number of data points collected. This study focuses on improving shallow ground temperature collection methods conducted in the Alvord Basin, Oregon and applying these improved methods to collect similar data in Yellowstone National Park, Wyoming. A temperature grid was resampled after significant rain events, confirming spatial correlation structures were unaffected by weather.
