Kate Mason also known as Nadagaat Tlaa Kaachgaawaa, married George Washington Carmack around 1889, or so she thought. After finding the gold in the Klondike and starting the whole Gold Rush thing, they became very wealthy and moved to Hollister California. Being away from home was not good for Kate or her daughter Gracie, as George left them and married someone else. Long sad story there, written up many places.
Kate returned home and on this day, March 29, 1920 she succumbed to the flu in Carcross and is buried in the little Carcross Cemetery. She was variously reported to have been born in either 1857, 1862 or 1869 in Tagish, perhaps.
