Tawani Wakawa Shoush

William Bernard Shoush (March 11, 1927 - January 4, 2002), also known as Tawani Wakawa Shoush, was an American author who wrote about Native American and Modoc-Klamath traditions, claiming Modoc lineage, including a popular story about his grandfather's encounters with Sasquatch (which he said were called Matah Kagmi) near Mount Shasta, California, and about theories regarding the Hollow Earth, toward which end he founded the International Society for a Complete Earth.
