Hot Lake, Oregon

[3] The first Europeans to see Hot Lake were the 32 members of an expedition under W. Price Hunt, who entered the Grande Ronde Valley on January 1, 1812, on their way to the mouth of the Columbia River.

[3] On August 7 of that year, Robert Stuart made the first written notation of the place while returning from the Columbia River.

[2][3] Hot Lake became a resting place for travelers, especially when settlers began traversing through the valley on the Oregon Trail in the 1840s.

[3] The first hotel was built at Hot Lake in 1864 by Samuel F. Newhard, and a post office was established in 1883.

[3] The resort began to decline in the 1930s, as a result of the death of its director since 1917, Dr. W. T. Phy, a disastrous 1934 fire, and the Great Depression.
