"The Yukon\u2013Tanana Terrane (YTT) is a tectonic terrane that extends from central Alaska through central Yukon and into northern British Columbia, Canada and Southeast Alaska, USA. Extending over 2000 km, the YTT is the largest tectonostratigraphic terrane in the northern North American Cordillera. The Yukon\u2013Tanana Upland is a physiographic province mostly underlain by rocks of the Yukon\u2013Tanana Terrane. Understanding and definition of the YTT is constantly progressing, the term \"Yukon Tanana composite terrane,\" or \"YTCT\" is used by some workers, reflecting the disparate depositional and tectonic histories being recognized in rock units within the YTT. Since 2010, some work dispenses altogether with the term Yukon\u2013Tanana Terrane, in favor of more detailed subdivisions."@en . . . . "-141.2030029296875"^^ . . . . . . .
