The Kateel, Koyukuk and Yukon Rivers were familiar to Madeline Solomon as a young girl.  Her Athabascan parents primarily lived a nomadic life hunting, trapping and fishing with Nulato serving as a home base.  Madeline spent her early years traveling with them except for a few years as a student at Holy Cross Mission. 

Madeline Solomon has a wealth of information about the Koyukon language and the old people who lived when she was a young woman.  She identified many archive photographs by Jesuit Priests in the early 1900’s, some of which appear in this book and other biographies.
