This is a report of investigations of the genetic structure of grayling populations in Yellowstone National Park and the Bighole River, Montana. This research is an extension of a comparative genetic study of Yellowstone National Park and Arctic grayling. This research was supported by the Rocky Mountain Parks Study Program. I appreciate the assistance of the personnel of Yellowstone National Park and Montana Fish and Game in obtaining the necessary samples. In particular J. Varley and R. Jones YNP are to be thanked for their assistance.
