Manufacturer's Description

Our Snow Crystal Card provides a stable base and grids for examining snow crystals. It also doubles as an Inclinometer by using the attached string and weight.

The Snow Crystal Card has laser etched textured 1 mm, 2 mm and 3 mm grids, inclinometer increments of 1 degree, crystal and snow pit "prompt legends" and centimeter and inch rulers.

During production, the high quality aluminum is partially textured and then anodized flat black for oxidation, contrast and for easy crystal identification. The metal has low thermal conductivity to minimize melting and preserve the crystals.

The Snow Crystal Card, a basic snow safety tool that will help in making an informed decision about the snowpack, is etched with information on snow crystal types.
