The historic town of Rocky Point was on the south side of the Missouri River in Fergus County, Montana, in the Missouri Breaks.
 Rocky Point was located at a natural ford on the Missouri River.
 In prehistoric times, American bisons trailed down through the breaks to Rocky Point to cross the river.
 During the Missouri River steamboat era (1860s to 1880s), the buffalo trail system leading to and from the ford caused Rocky Point to become a steamboat landing, which received freight for mining camps in the Judith Mountains (to the south) and in the Little Rocky Mountains (to the north) and also for Fort Maginnis built in 1880.
 In the 1870s and 1880s, Rocky Point had a store, hotel, two saloons, a feed stable, a blacksmith shop and a ferry.
 Due to its remote location in the Missouri Breaks, in the 1870s and 1880s Rocky Point became a refuge for outlaws who turned to rustling cattle and horses until rancher-vigilantes took punitive action in 1884.
 From 1886 to 1936 it had a post office near by which was known as Wilder and so the community of Rocky Point was sometimes also called Wilder.
 The community at the Rocky Point ford continued through the homesteading years from 1900 to 1918, but faded away when the ferry ceased to function in the 1920s, and it finally disappeared in 1936 when the Army Corps of Engineers condemned and bought up land adjacent to the Missouri River that might possibly be affected by Ft Peck Dam, then being built.
 Today some historic but deteriorating structures still remain on the site, which is now on the Charles M. Russell National Wildlife Refuge operated by the U.S. Fish and Wildlife Service.
 Being on public lands the Rocky Point ford area may be approached by "dirt" roads and visited, but the roads become impassable when wet.
Long Lake Wetland Management District encompasses three counties in south-central North Dakota, an area famed for its wealth of waterfowl-producing potholes and native prairie grasslands. Headquarters for the Wetland Management District is located in the Long Lake National Wildlife Refuge office near Moffit, North Dakota, which is about 35 miles southeast of Bismarck.
 Topographical landforms of the area include Missouri Coteau and Missouri River Slope.
 Precipitation averages just under 16 inches per year.
 Approximately 68 percent of the land in the three county area remains virgin sod - native mixed-grass prairie.
 The dominant land use is cattle grazing.
 The Coteau wetlands found in the northeastern portion of the Wetland Management District are classic prairie potholes of various sizes and types that are prime duck production habitat.
 These areas, when wet, are very productive.
 Soils in this area are generally deep and quite productive.
 Due to the rolling nature of the landscape on the Coteau, a lot of the land is also characterized as highly erodible.
 Conversely, many of the wetlands on Missouri River Slope portion of the Wetland Management District are large semi-permanent and permanent alkali wetlands.
 There are 21 wetland sites on the Missouri River Slope that have a history of periodic avian botulism outbreaks.
 These areas occasionally present localized problems for significant numbers of migratory birds.
 Soils on the Missouri River Slope are characteristically shallow with high proportions of sand and gravel.
 Much of the land is highly erodible.
 Since 1985, substantial land acreage in the three county area that was once farmed has been retired to Conservation Reserve Program grasslands.
 The program has assisted in restoring waterfowl populations for many species in the Wetland Management District which exceed the highest level ever recorded since surveys began.
The Cracon du Nez (also known as Gross Condunez) occasionally also misspelled (on Google Maps and Google Earth) as the Crocon du Nez, is a sharp sided ridge that divides the Teton River and the Missouri River in Chouteau County, Montana (47.874719° -110.598212°), at a point where the increasing erosion at a large bend of the Missouri River has caused the two rivers to be a mere third of a mile (about 650 yards) apart.
 The Cracon du Nez ridge is an example of Missouri River stream bank erosion developing toward a future "stream capture" of the Teton River flow.
 A trail runs along the top of the ridge, where in 1865 Little Dog, a chief of the Piegan Blackfoot tribe was ambushed and killed by rebellious and jealous warriors from his own Piegan band.
 An abandoned railroad tunnel runs under the ridge, part of the former Montana Central Railway branch line of the Great Northern railroad running from Havre to Fort Benton, Great Falls, Helena and Butte.
 U.S. Highway 87 passes by the ridge and allows the traveler to see the Cracon du Nez.
 The name is derived from the French and means bridge of the nose, and was probably given by the French boatmen who comprised keelboat crews in the fur trade in the upper Missouri River in Montana during the early decades of the 1800s.
The 2011 Missouri River floods was a flooding event on the Missouri River in the United States.
 The flooding was triggered by record snowfall in the Rocky Mountains of Montana and Wyoming along with near-record spring rainfall in central and eastern Montana.
 All six major dams along the Missouri River released record amounts of water to prevent overflow which led to flooding threatening several towns and cities along the river from Montana to Missouri; in particular Bismarck, North Dakota; Pierre, South Dakota; Dakota Dunes, South Dakota; South Sioux City, Nebraska, Sioux City, Iowa; Omaha, Nebraska; Council Bluffs, Iowa; Kansas City, Missouri; Jefferson City, Missouri, as well as putting many smaller towns at risk.
 According to the National Weather Service, in the second half of the month of May 2011, almost a year's worth of rain fell over the upper Missouri River basin.
 Extremely heavy rainfall in conjunction with an estimated 212 percent of normal snowpack in the Rocky Mountains contributed to this flooding event.
Cow Creek is a tributary of the Missouri River, approximately 35 mi long, in north central Montana in the United States.
 Cow Creek rises in the southern foothills of the Bear Paw Mountains in western Blaine County and flows east and then south, joining the Missouri approximately 25 mi northeast of Winifred, Montana—or 22 mi upstream from the Fred Robinson Bridge.
 Cow Creek flows down to the Missouri in a canyon that passes through the Missouri Breaks, which are severely eroded badlands that extend out on either side from the Missouri River.
 The floor of Cow Creek canyon provided a pathway of travel from the Montana plains north of the river, down to the Missouri – at the mouth of Cow Creek, Cow Island made fording the Missouri easier – a steep but short trail on the south bank of the Missouri opposite Cow Creek completed this route which led from the northern Montana plains to the central and southern Montana plains.
 This pathway was used by migrating buffalo/bison and nomadic American Natives for centuries.
 During the steamboat era on the Missouri River, when low water prevented riverboats getting up to Fort Benton, the mouth of Cow Creek became a river landing and freighting depot, and it was the start of the Cow Island Trail by which freight was moved on to Fort Benton by going north up Cow Creek and then west.
 In 1877 the Nez Perce Indian Tribe, fleeing to Canada, had several skirmishes along Cow Creek including the "Battle of Cow Island", and several days later at a camp on Cow Creek the Nez Perce, thinking themselves now beyond the reach of the U.S. Army, made the fateful decision to slow down, rather than push on for the Canada–US border.
 Today, modern highways have by passed Cow Creek, and the buffalo and the nomadic Indian are gone.
 Cow Creek is dormant, in one of the most remote spots of the isolated regions of the vast area known as the Montana Missouri Breaks.
The Boonslick, or Boone's Lick Country, is a cultural region of Missouri along the Missouri River that played an important role in the westward expansion of the United States and the development of Missouri's statehood in the early 19th century.
 The Boone's Lick Trail, a route paralleling the north bank of the river between St. Charles and Franklin, Missouri, was the primary thoroughfare for settlers moving westward from St. Louis in the early 19th century.
 Its terminus in Franklin marked the beginning of the Santa Fe Trail, which eventually became a major conduit for Spanish trade in the American Southwest.
 Later it connected to the large emigrant trails, including the Oregon and California Trails, used by pioneers, gold-seekers and other early settlers of the West.
 The region takes its name from a salt spring or "lick" in western Howard County, where Nathan and Daniel Morgan Boone, sons of famed frontiersman Daniel Boone, built a homestead in 1807.
Boyer Chute National Wildlife Refuge, created in 1992, is a National Wildlife Refuge (NWR) located along the banks of the Missouri River in the U.S. state of Nebraska.
 The 4040 acre refuge preserves an area that had been cultivated and neglected before the early 1990s.
 Channelization projects along the Missouri River to improve flood control and navigation resulted in the closing off a side branch of the river, known since the early 19th century as Boyer Chute.
 Between 1820 and 1937 the Missouri River had migrated 3 mi eastward and the area of the chute had originally been on the east bank of the river; today, the chute is west of the main channel of the Missouri.
 In 1937, the Army Corps of Engineers began to rechannel portions of the Missouri River, cutting off the chute to flowing water.
 Overgrowth and cultivation took over the lands now preserved in the refuge.
 Restoration of the area commenced in 1993; this included planting 9,100 native plants and trees and restoring the inflow to the chute from the main channel of the Missouri River.
The Oregon Trail is a 2170 mi historic east–west, large-wheeled wagon route and emigrant trail in the United States that connected the Missouri River to valleys in Oregon.
 The eastern part of the Oregon Trail spanned part of the future state of Kansas, and nearly all of what are now the states of Nebraska and Wyoming.
 The western half of the trail spanned most of the future states of Idaho and Oregon.
David O. Quick (August 27, 1829 – December 1910) was an American educator and politician in the state of Oregon.
 A native of Indiana and a trained lawyer, he crossed the Oregon Trail where he was a school teacher and later farmer.
 He served one term as a Republican in the Oregon House of Representatives.
The Montana Dinosaur Trail is a series of fourteen dinosaur-themed museums, state parks and other attractions in twelve communities located in the central and eastern regions of the state of Montana in the United States of America.
 The trail, a plan to increase attendance at the region's museums and drive tourism in general was established via the work of a number of museums as well as community and state officials.
 The idea for a trail uniting the museums and promoting tourism in eastern Montana came from a meeting of the Missouri River Country board of directors at the Dinosaur Field Station in Malta, Montana and the trail was officially launched via the efforts of the tourism groups of: Custer Country, Missouri River Country, Russell Country and Yellowstone Country; two state agencies: Fish, Wildlife and Parks and Travel Montana; and two federal agencies: the Army Corps of Engineers and the Bureau of Land Management.

Question: The trail that D.O. Quick crossed connected the Missouri River to what?
Answer: valleys in Oregon
