Verdigris River, a stream of southeastern Kansas, has a history dating hack considerably over a century. It is mentioned by Pike at the time of his visit to that section in 1806 and also by Nuttall in 1818. The river flows through a rich country that in early days produced much in the way of furs. A number of trading houses were located along its course from time to time, the most important of which was probably that operated by a man named Glenn in 1819, located at a point about a mile above its confluence with the Arkansas river. Clermont's band of Osage Indians was located on the stream about this time and is mentioned by S. H. Long in his travels. By the treaty of 1834 with the Cherokee Indians the Verdigris river was named as a part of the boundary of their lands. The stream has its source in several small streams, one of which rises in eastern Chase county, one in northern Greenwood county and two in southern Lyon county. It flows in a southeasterly direction across Greenwood county, the extreme southwestern corner of Woodson county, Wilson and Montgomery counties, entering Oklahoma almost due south of Coffeyville. From there the stream flows through the counties of Nowata, Rogers and Wagoner, Okla., uniting with the Arkansas river near the town of Wybark, about 3 miles from Fort Gibson. Among the more important tributaries of the Verdigris are Willow, Homer, Sandy, Drum, Big Hill, Pumpkin and Onion creeks, and Paw and Fall rivers in Kansas, and Big Caney and Little Verdigris rivers, Bird creek and about two dozen smaller streams in Oklahoma. The estimated length of the stream is about 270 miles, a little over one-half of which is in Kansas.
