The following images were obtained using a Low Temperature Scanning Electron Microscope (LT-SEM)
that is located in the Beltsville Agricultural Research Center in the Electron Microscopy Unit,
Bld. 465, Beltsville Maryland 20705. Information gained from studying the structure of snow is vital
to several areas of science as well as to activities that affect our daily lives and is only one of several
agricultural research projects that are currently being pursued in this research unit.
