Arthur Treadwell Walden (May 10, 1871 – March 26, 1947) was a Klondike Gold Rush adventurer, author, dog driver and participant in the first Byrd Antarctic Expedition.

[1] Disliking city life in Boston, Arthur went to live at his father's vacation home in Tamworth, New Hampshire.

During the gold rush, Walden found himself working as a freighter carrying supplies and mail down the Yukon River.

Walden would only agree to accompany Byrd if he guaranteed that no dogs would be shot to save supplies, as had been done in previous expeditions to the Arctic.

[6] During the expedition, Walden and his 13 dogs moved thousands of pounds of supplies from the ship over the 16 mile trail to base camp.

[5] Chinook, the progenitor and namesake of the breed, mysteriously disappeared on January 17, 1929, while moving supplies to base camp, and was presumed to have died.
