Abstract

Following are some comments concerning Dr. Steenland's discussion of gravity data in Professional Papers 316-A and 316-C of the U.S. Geological Survey. Dr. Steenland's cylinder calculations are entirely dependent upon the regional anomaly removed. He obtained an anomaly of -40 mgal over Paradox Valley, whereas we obtained a residual anomaly of -32 mgal. The bottom 4,000 ft of Dr. Steenland's cylinder contribute -5 mgal to the anomaly. Dr. Steenland's analysis supposes that the only effective density contrasts are those attributable to variations in salt thickness or isostatic compensation.
