This is to announce a website regarding lunar crater depths for approx 2,300 smaller nearside craters made during the Apollo era. Approximately 1,896 higher-precision nearside crater depths from the Apollo era by Pike (1976) and Arthur (1974) and 477 low-precision crater depths by Cherrington (1969) were digitized and are presented here for amateur lunar enthusiasts' use. Pike (1976) and Arthur (1974) report a kilometer precision to two significant digits for crater diameters and crater depths. The standard source of the USGS Gazetteer of Planetary Nomenclature reports only crater diameters in whole kilometers. The Gazetteer does not report crater depths. Another standard reference source for crater depths and diameters is the Appendix in Westfall's Atlas of the Lunar Terminator (2000). Westfall's Appendix table concerns about 830 named-craters but reports no depths or diameters for smaller satellite feature craters. In the table presented here, 1,637 (69%) smaller satellite depths and diameters are digitized; 684 (29%) larger named-crater and other feature measurements from Cherrington (1969), Arthur and Pike are digitized. Appendix in Westfall (2000) remains the best source for named crater depths. The Cherrington chart take-offs from the 1960s have a very low accuracy. This digitized table provides higher-precision supplemental measurements for smaller satellite craters measured during the Apollo era. The table, by feature name, can be directly linked from: http://members.csolutions.net/fisher...atureName.html Arthur (1974) is a portion (N=1,900) of the 7,000 plus nearside crater catalogue prepared by Chuck Wood in the 1970s, discussed in this LPOD: Wood, C.A.
