Question: The Shawnee Trail was a segment of a network of trails whuch ran through what valley?
Context: Ventu Park Open Space is a 141-acre open space area in Newbury Park, California.  Its primary features are the Rosewood Trail leading to Angel Vista, a 1,603 ft peak in the Santa Monica Mountains.  Parking for the Rosewood Trail is located at the Stagecoach Inn Park, across Lynn Road from the primary trailhead.  The Rosewood Trail begins with oak woodland and crosses a creek at the canyon floor, before climbing up towards the steep Angel Vista Point.  There are 360-degree panoramic views of the Conejo Valley, the Oxnard Plain, the California Channel Islands, Pacific Ocean, Point Mugu, Hidden Valley, as well as the Santa Monica-, Santa Susana- and Topa Topa Mountains.  The Rosewood Trail is the starting point for the Los Robles Trail, the longest trail operated by the Conejo Open Space Conservation Agency (COSCA).  It connects to various open space areas and nature preserves in the Greater Thousand Oaks Area, including the Hope Nature Preserve, Los Padres Open Space, Conejo Ridge Open Space, Deer Ridge Open Space, Old Conejo Open Space and Los Vientos Open Space.  The 25-mile Los Robles Trail begins by Angel Vista Point and is a 25-mile trail connecting Newbury Park and the City of Westlake Village by crossing Hidden Valley, Thousand Oaks and Lake Sherwood.  Alternatively, hikers can cross the Potrero Ridge and join the trail leading to Satwiwa, which again connects to Point Mugu through trails crossing the Santa Monica Mountains through the Big Sycamore Canyon.  The trails here are used by equestrians, mountain bikers as well as hikers.  The Rosewood Trail is a 5-mile roundtrip hike from the Stagecoach Inn Park to the top of Angel Vista. William Field Memorial Hart-Montague Trail State Park, previously and more commonly known as Hart-Montague Trail State Park, is a linear state park in Michigan that consists of a bicycle trail running from the city of Montague in Muskegon County to the city of Hart in Oceana County.  Recognizing its potential, Bill Field of Shelby purchased the former railroad and donated it for trail use to the State of Michigan.  Opened in 1991 and officially adopted as a Rails to Trails park in 1996, it was one of the first "Rails to Trails" projects in the State of Michigan.  Its success paved the way for more trails throughout the state and Midwest.  The trail's total length was previously 22 mi ; however continuous expansions have increased that length in recent years with the hope of linking it to other trails throughout Western Michigan.  A number of local businesses, such as restaurants and ice cream parlors, in the towns along the trail have posted small, discreet signage near the trail to attract cycling visitors who might not otherwise ever notice the little shops in the intervening small municipalities.  A whimsically themed ice cream/dairy bar in New Era, roughly halfway along the trail, is often mentioned by trail visitors, although there are also a number of others spread along the trail.  There is a bicycle rental shop on Thompson St in Montague in the south, a repair shop right off the trail in Mears as well as another rental shop on Silver Lake Rd in Mears several miles away from the northern section of the trail. Mānoa Falls Trail is a 1.6 mile trail on the island of Oahu in Hawaii.  The trail is a part of the Honolulu Makau Trail System, and leads to a popular 150 foot waterfall called Manoa Falls.  Hiking the trail is approximately a one-hour round trip.  Many tourists are attracted to the waterfall and scenery throughout the trail.  The trails have a history as one of the earlier Hawaiian trails.  There are many legends of the Night Marchers, or ancient Hawaiian warriors associated with Manoa Falls.  Scenes in movies such as Jurassic Park and Catching Fire were filmed at Manoa Falls.  The Manoa Falls trail harbors many native Hawaiian plant species and tropical birds as well.  The Lyon Arboretum, located in the Manoa Valley at the base of the trail is another popular tourist attraction and aims to preserve endangered Hawaiian plants.  Rain showers are very common in on the trail and the path to the waterfall is often muddy and slippery.  Flash floods may also occur at any time.  Swimming in the pools of water on the trail is highly discouraged due to the threat of Leptospirosis. The Sauk Trail began as a Native American trail running through Illinois, Indiana and Michigan in the United States.  From west to east, the trail ran from Rock Island on the Mississippi River to the Illinois River near modern Peru then along the north bank of that river to Joliet, and on to Valparaiso, Indiana.  Then it ran northeasterly to La Porte and into southern Michigan running through Niles, Three Rivers, Ypsilanti, and ending at the Detroit River near Detroit.  There is a suggestion that sections of the trail followed the southern boundary between the dense forest and the mixed grassland regions.  The presence of a mastodon trailway along the same path indicates that the Native Americans may have been using a long established game trail.  Henry Schoolcraft, at present-day Michigan City, Indiana, in 1820, describes the trail, as a "plain horse path, which is considerably traveled by traders, hunters, and others..." and said that a stranger could not follow it without the services of a guide because of the numerous side trails.  The Sauk Trail intersected many important trails and early roads including the trails to Vincennes, to Green Bay, to Fort Wayne and to Little Traverse Bay. The Waterloo-Pinckney Trail is a 36-mile-long hiking trail which runs through Waterloo State Recreation Area and Pinckney Recreation Area in southeastern Michigan, United States.  Part of the trail also passes through Park Lyndon County Park.  The trail travels through glacial features such as eskers and kettle lakes as well as swamps and open meadows remaining from abandoned farmlands.  Forest types include oak and pine.  The trail tops out at 1,128 ft on Sackrider Hill, 208 ft above surroundings, the largest elevation gain.  Other hills and ridges give 50 to rises.  The trail is blazed with blue triangles and at some points shares trails with the Potawatomi Trail and the nature trails around the Eddy Discovery Center.  Part of the trail is open to mountain biking and horseriding and hunting is allowed in most areas along the trail.  The trail has several nearby campgrounds allowing it to be hiked as a 2, 3 or 4 day trip.  Side trails to the campgrounds make the entire trip 38.5 mi . The Texas Road, also known as the Shawnee Trail, Sedalia Trail or the Kansas Trail, was a major trade and emigrant route to Texas across Indian Territory (later Oklahoma, Kansas and Missouri).  Established during the Mexican War by emigrants rushing to Texas, it remained an important route across Indian Territory until Oklahoma statehood.  The Shawnee Trail was the earliest and easternmost route by which Texas Longhorn cattle were taken to the north.  It played a significant role in the history of Texas, Oklahoma, Missouri and Kansas in the early and mid-1800s. The Great Texas Coastal Birding Trail is a state-designated system of trails, bird sanctuaries, and nature preserves along the entire length of the Texas Gulf Coast in the United States.  As the state of Texas hosts more bird species than any other in the U.S. the trail system offers some of the most unusual opportunities for bird-watching in the world.  The "trail" is actually 43 separate hiking and driving trails that include 308 birding sites.  The sites themselves feature a variety of viewing opportunities with boardwalks, observation decks, and other amenities.  The trails boast more than 450 bird species.  The trail system is managed by the Texas Parks and Wildlife Department as part of the Great Texas Wildlife Trails which also include the Heart of Texas Wildlife Trail, the Panhandle Plains Wildlife Trail, and the Prairies and Pineywoods Wildlife Trail. Root River State Trail is a 60 mi paved multi-use rail trail system in southeast Minnesota.  The trail system consists of two main segments, the Root River segment, and Harmony-Preston Valley segment.  The trails are used mainly for bicycling, hiking, and inline skating in the summer, and for cross country skiing in the winter.  Much of the trail, especially the Root River segment, is built along a former Milwaukee Road (Chicago, Milwaukee, St. Paul and Pacific Railroad) railbed following the contours of the Root River valley. The Great Indian Warpath (GIW)—also known as the Great Indian War and Trading Path, or the Seneca Trail—was that part of the network of trails in eastern North America developed and used by Native Americans which ran through the Great Appalachian Valley.  The system of footpaths (the Warpath branched off in several places onto alternate routes and over time shifted westward in some regions) extended from what is now upper New York state to deep within Alabama.  Various Indians traded and made war along the trails, including the Catawba, numerous Algonquian tribes, the Cherokee, and the Iroquois Confederacy.  The British traders' name for the route was derived from combining its name among the northeastern Algonquian tribes, "Mishimayagat" or "Great Trail", with that of the Shawnee and Delaware, "Athawominee" or "Path where they go armed". The Shawnee Trail was the white settlers' name for an American Indian trail in what is now eastern West Virginia, USA.  It was a segment (or branch) of the much larger Indian trail network known as the Great Indian Warpath, which stretched from New York to Alabama.  The GIW was referred to from this point north as the "Seneca Trail".  Thus, in pioneer days, the segment known as the Shawnee Trail was often also referred to as the Seneca Trail.
