Question
How can the relationship between snow water equivalency and snow depth predict or model precipitation in the region’s past?
How can a cross-section of snow pack be used as a snapshot of weather?
Hypothesis
We think we will find that different locations will affect the snow water equivalence because the elevation, wind, and other weather factors all contribute to the SWE.
Experimental Design
We want to make two snow pits in two different locations of similar depth. After routine test on the pits we will determine SWE (Snow Water Equivalency) and layers. We will determine the different layers by sliding a card from top to bottom and marking the different densities with popsicle sticks and determine SWE by using this equation:
1x (density/100)x height.

Conclusions
Hypothesis is valid – Data is inconclusive
Limited by our methods
Valid design
Future application
Reflections
If we were to have more time to perform this experiment we would have been able to have more precise data, a greater sample size, and more time to reflect and process our outcomes,
We would have also dug our snow pits to the ground in order to stay consistent,
We also are curious how the snow fall and metamorphism changes in different locations. (specifically different areas of Brundage Mountain)
