Question: Traveler's Rest is a stopping point of the trail that has what elevation?
Context: Fort Laramie (founded as Fort William and then known for a while as Fort John) was a significant 19th century trading post and diplomatic site located at the confluence of the Laramie River and the North Platte River in the upper Platte River Valley in the eastern part of the U.S. state of Wyoming.  It was founded in the 1830s to service the overland fur trade during the middle 19th century.  It sat at the bottom of the long climb leading to the best and lowest crossing point at South Pass into western descending valleys and so was a primary stopping point on the Oregon Trail.  Along with Bent's Fort on the Arkansas River, the trading post and its supporting industries and businesses were the most significant economic hub of commerce in the region. Kettleman City is a census-designated place (CDP) in Kings County, California, United States.  Kettleman City is located 28 mi southwest of Hanford, 54 miles (88 km) south of Fresno, at an elevation of 253 feet , and sits only about 1/2 mile North of the 36th parallel north latitude.  It is part of the Hanford–Corcoran Metropolitan Statistical Area.  The population was 1,439 at the 2010 census, down from 1,499 at the 2000 census.  Kettleman City is near the halfway point between Los Angeles and San Francisco or Sacramento on Interstate 5 at Exit 309, and thus is a major stopping point for food and lodging. Gauley Bridge is a town in Fayette County, West Virginia, United States.  The population was 614 at the 2010 census.  The Kanawha River is formed at Gauley Bridge by the confluence of the New and Gauley Rivers.  Two miles to the southeast of Gauley Bridge, in Glen Ferris, West Virginia, is Kanawha Falls, a popular stopping point on Midland Trail Scenic Highway. Hedge Creek Falls is a waterfall on hedge creek, in the Shasta Cascade area in Dunsmuir, California.  There is a small cave located behind the waterfall, allowing visitors to walk behind the cascading water.  Shortly after the waterfall, hedge creek flows into the Sacramento River south of Mossbrae Falls.  There is a viewing platform over the river, with a view of Mount Shasta.  Access to the waterfall and viewing platform is via a short hiking trail.  The trail starts at a small park off the Dunsmuir Ave/Siskiyou Ave exit on Interstate 5.  The close proximity to Interstate 5, makes the waterfall a very popular stopping point for passing motorist. A waypoint is an intermediate point or place on a route or line of travel, a stopping point or point at which course is changed, first use of the term tracing to 1880.  In modern terms, it most often refers to coordinates which specify ones position on the globe at the end of each "leg" (stage) of an air flight or sea passage, the generation and checking of which are generally done computationally (with a computer or other programmed device). Arrow Rock Historic District is a National Historic Landmark District encompassing the village of Arrow Rock, Missouri and the adjacent Arrow Rock State Historic Site.  The Arrow Rock area was where the historic Santa Fe Trail crossed the Missouri River, and was thus a key stopping point during the settlement of the American West.  The 260 acre historic district was declared a National Historic Landmark in 1963. Lolo Pass, elevation 5233 ft , is a mountain pass in the western United States, in the Bitterroot Range of the northern Rocky Mountains.  It is on the border between the states of Montana and Idaho, approximately 40 mi west-southwest of Missoula, Montana. The trail start at Lukla and Phakding is often the main stopping point for trekkers on their way to Mount Everest via the Gokyo Ri route or Tengboche route. The trail start at Lukla and Jorsale is the last settlement before Namche, the main stopping point for trekkers on their way to Sagarmartha (Mount Everest), one of the UNESCO World Heritage Site since 1979, via the Gokyo Ri route or Tengboche route. Traveler's Rest was a stopping point of the Lewis and Clark Expedition, located about one mile south of Lolo, Montana.  The expedition stopped from September 9 to September 11, 1805, before crossing the Bitterroot Mountains, and again on the return trip from June 30 to July 3, 1806.  Traveler's Rest is at the eastern end of the Lolo Trail.  It was declared a National Historic Landmark in 1960 and added to the National Register of Historic Places in 1966.  The boundaries were subsequently revised, and mostly lie within the 51 acre Traveler's Rest State Park, which is operated by the Montana Fish, Wildlife & Parks.  Significant archeological findings made in 2002, including latrine sites with traces of mercury and fire hearths, make this the only site on the Lewis and Clark National Historic Trail that has yielded physical proof of the explorers' presence.  Records made by Lewis and Clark often spell "Traveler's" as "Traveller's".  This spot is largely unchanged from the days of Lewis and Clark.  From this location, Lewis and Clark split up to explore Montana during their return trip, not reuniting until they reached Sanish, North Dakota.
