Large yellow/pale green mount with title and "No. 190" printed on a label on verso. On a Powell and Thompson survey mount. This shows Powell's boat the "Emma Dean," with his chair. Taken in August 1872 by John Hillers. At the extreme right there appears to be a bottle [for chemicals?] and perhaps the edge of the darktent. The marking at the extreme lower right of the right view looks printed, but is in ink.
