In 1908, Beaton began
prospecting near
Iditarod, Alaska, with his partner William A. Dikeman. Following an unavailing summer, they left the camp and drove a
steam launch as far up the
Iditarod River as they could manage. They beached the boat and built a cabin about south of Iditarod. On Christmas Day 1908, Beaton, Dikeman, and John's brother Murdock struck gold near the head of Otter Creek. By the summer of 1909, news of the find had spread, and other prospectors began to claim the remaining ground around Otter Creek, and founded a nearby camp named
Flat. By the spring of 1910, the boomtown had a population of over 2,000. Otter Creek was eventually found to contain the widest
paystreak ever mined in Alaska, and the area became the third-largest Alaskan
placer mining site, after
Fairbanks and
Nome. Around 1937, Beaton sold his claims at Otter Creek, and began dredging on Ganes Creek in the Innoko District until World War II. == Personal life ==
