Comparison of depth hoar crystal using light (video) and Low Temperature Scanning Electron Microscopy


Example of a depth hoar crystal collected from the base of a snowpit in Wyoming. Comparison of video and Low Temperature Scanning Electron Microscopy images of the identical crystal illustrates that the faceting and internal features in the video image are somewhat compromised by the transmitted, reflected and refracted light that occurs with the light microscope. The external features are more distinct in the Low Temperature Scanning Electron Microscope image.
