According to "Yukon/Charley Rivers National Preserve, Cumulative Impacts of Mining: Environmental Impact Statement, Volume 1" the town of Derwent was established in 1898 near the mouth of the Charley River. Like many mining towns, it was short-lived. The Klondike Gold Rush National Historical Park in Skagway holds the journal of William Tracy James, the man pictured with the dog (named "Dad") at the far right of the photograph. James' diary entry from August 23, 1899 details Pillsbury's visit to take the photograph at Derwent. "I started for Derwent at 7:50 AM and reached here at 6:30 PM. I found a Mr. Pillsbury, a photographer running down the Yukon taking views for the government. He was so struck by [my] head of hair, he wanted a picture of it so took a view of our cabin with Carl, Jack, Othmier, Fisher and I standing in front. We bought 9# rice for $1.80, 7# sugar for $1.40, 3# corn meal for 45 c., 6 cans St. Charles cream $2.00, 4 cans fruit $1.55 and we paid him from the vial of dust we got for a sack of flour above Dawson." James was 21 years old when the photograph was taken.; "Prospectors" at Derwent, Chirley [sic] Ri. [Symbol.] No. 625.; Location approximated near the mouth of the Charley River where it meets the Yukon River. The exact location of Derwent is unknown.
