These layers show a record of the eruption's size and intensity, allowing geologists to estimate the rate of activity. Ideal for teaching students about rounding and sorting, as well as for identification and classification exercises. While each specimen will vary slightly in shape, size, and color, it will measure approximately 1" in length. Each is individually packaged, labeled, and barcoded for easy identification and storage.
