Thank you, Scotty, my friend!
I think that you really are the world's foremost authority in hands-on polar philately, after handcancelling, with various pictorial postmarks, over 10,000 philatelic items for collectors from around the world, while working many summers and winters, until 2008, in Antarctica as official USA Mail Clerk/Postmaster.
"Chapel of the Snows is a non-denominational Christian church located at the United States McMurdo Station on Ross Island, Antarctica. The chapel is the southernmost religious building in the world and has regular Catholic and Protestant services. During the Austral Summer, the chapel is staffed by rotational chaplains. The U.S. Air National Guard supplies Protestant Chaplains and the Archdiocese of New Zealand supplies Catholic Priests. The chapel is also host to services and meetings for other faith groups such as Latter Day Saints, Baha'i, and Buddhism and non-religious groups such as Alcoholics Anonymous."
