Evolutionists generally assume that dripstone deposits, such as stalactites and stalagmites, form slowly, while creationists would maintain that rapid rates of formation must be possible. Here factors affecting the rate of formation of dripstones are discussed. Hypothetical environmental conditions immediately following the Genesis flood would be expected to produce rapid formation of dripstone. Actual observations of rapid formation are reported. Therefore, the creationist position is supported by theoretical as well as experimental data relating to the rate of formation of dripstone.
