Member nations of UNESCO submit tentative lists of sites within their countries that may be nominated for recognition as World Heritage Sites. The U.S. is now being updated for the first time since 1990. The National Park Service is responsible for compiling the new list, and asked for inputs from the U.S. National Commission for UNESCO as part of the compilation process. A NatCom committee was formed to review the submission, and met held a phone consultation a couple of weeks ago. The minutes of the meeting provide a list of the potential sites considered this year, and the recommendations for inclusion or non-inclusion from the list.
White Sands was one of the sites highly recommended for inclusion on the tentative list.
