 Yes.   
www.hollowplanets.com is the website of Jan Lamprecht, who wrote the book I recommended, “Hollow Planets”.   He did cover several earlier artic explores including Dr. Cook and his photo of Bradley Land, Commander Peary and Crocker Land, and his chapters cover a unique type of mirages called polar ‘superior mirages' because they are seen upside down.
