Peter Skene Ogden was a mountain man and trapper for whom Ogden City, North Ogden, Ogden River, Ogden Valley, and Mount Ogden were named, and Brigham Young first proposed naming Ogden City for him in 1850. In this area, between May 23 and 25, 1825, the only hostile encounter between American and British fur trappers took place, known as the encounter at Mountain Green or Deserter Point. Ogden, one of the most capable and successful brigade leaders of the British Hudson's Bay Company, camped here after an extraordinarily successful six-day hunt in Ogden's Hole, the mountain valley about 8 miles north, where his brigade of 131 persons, including trappers' squaws and half-breed children, with 268 horses and 352 traps, took more than 80 prime beaver per day. The brigade had been sent here as part of a British policy to make the Oregon Territory unattractive to American trappers by removing all the beaver. Camped within 100 yards was a rowdy group of American free trappers who resented the British presence on what they called American soil. Under the vocal leadership of Johnson Gardner, 25 Americans and 14 deserters from Ogden's brigade, all well armed, rode into Ogden's camp, demanded that the British leave American territory, declared freedom and protection for brigade members who wished to join them, and offered $3.50 per pound for pelts, eight times the price paid by the Hudson's Bay Company. After two days of these inducements, Ogden lost 23 of his free trappers and more than 700 pelts to the Americans. To avoid a longer mutiny and a possible shootout, he broke camp and returned north by the same route he had come, and no Hudson's Bay trapper ever went south of this point again. The irony was that both the American and British trappers were south of the jointly occupied Oregon Territory, which lay north of the 42nd parallel; in 1825, everyone present here was trespassing on Mexican territory that did not become American until the Treaty of Guadalupe Hidalgo in 1848.
