Soda-Niter in North Central Arizona Earth Cracks
Carol A. Hill and P. Gary Eller


Soda-niter (NaNO3) occurs as bitter tasting, white efflorescent crusts in Malmquist and Dangling Flake Fissues, Wupatki National Monument, North Cental Arizona, and in Buffalo Crack, approximately 15 km southeast of the Monument. The occurrence of this comparatively rare mineral is related to the low relative humidity of these caves.
