D. Watson (in letter of January 16, 1957) wrote: "When Jack Wade, now
Chief Ranger, was doing patrol work in the Mancos Canyon back in the
1930's, he saw mink along the river at the east side of the Park.
Several years ago, the people who lived on the ranch where Weber Canyon
joins the Mancos trapped a mink." Tracks have been reported along the
Mancos River in several years.
