Prairie Snow Tube

The Prairie-type Sampler is manufactured with an ALUMINUM tube and has a 30 sq.cm. cutter. The tube is 4 feet (1.2 meters) long, 2 5/8 inches (6.67 cm) i.d. and is marked in both English and metric units for measuring the depth of snow pack. The tube meets USGS standards for noncontamination when the core will be retained for water quality analysis. Aluminum-type models should not be used for collection of water quality samples.

The scale is marked in equivalent water depths in both English and metric units, to a maximum of 25 inches in 1/4 inch increments and 63.5 cm in 0.5 cm increments. The scale is interchangeable with earlier model Prairie tubes of the same inside diameter.
