DescriptionOtter Creek flows north into Montana out of the highlands in Wyoming and empties into the Tongue River at Ashland. Capt. Calvin Howes developed one of the earliest ranches on Otter Creek. He arrived in Montana in the early 1880s and established the Circle Bar O Ranch on the lower Powder River. In 1884, Captain Howes drove 2,000 head of cattle from Texas to Otter Creek and maintained a successful cattle operation that survived the disastrous winter of 1886–87. The creek’s naming is attributed to Howes.Personal NamesHowes, CalvinContributing InstitutionMontana Historical Society Library and ArchivesGeolocation[1]
