From June 22 through July 20, additional data was gathered on the distribution of Microtus richardsoni. Colony sites in the high country of the Teton Mountains were visited for comparison with the colonies situated near Togwotee Pass. Additional information was gathered on the habitat preferred by this species as well as on molting stages in young animals. The results of this study are currently being compiled for publication, the final draft of which will constitute a complete report. Project Number 87.
