Haletown (also known as Guild) is an unincorporated community in Marion County, Tennessee, United States. It is part of the Chattanooga, TN–GA Metropolitan Statistical Area.

The Marion Memorial Bridge was a 4-span metal truss bridge that formerly carried U.S. Route 41 in Marion County, Tennessee over the Tennessee River and Nickajack Lake. It was built in 1929. The main span was 369 feet (112 m), and the bridge had a total length of 1,870 feet (570 m). The bridge was listed on the National Register of Historic Places on October 25, 2007. The bridge featured an unusual truss configuration that is a hybrid of the Parker and K-Truss configurations. The bridge was replaced by a new concrete and box girder span that opened in November 2014, slightly delayed from its target completion date of August 2013 by conditions encountered in the construction of the replacement bridge footings. Since the construction of the new bridge's footings involved blasting within 30 feet (9.1 m) of the Marion Memorial Bridge, state officials closed the bridge to vehicle and pedestrian traffic on January 9, 2012, with traffic being re-routed to the Interstate 24 bridge south of the span. The metal trusses of the bridge were demolished and removed by June 2015. The bridge was delisted from the National Register in June 2016. Some people in the community expressed the desire to preserve the bridge in some way. Tennessee Department of Transportation officials said the bridge was costly to maintain, citing as an example the repainting cost of $1 million.This bridge was built before the construction Nickajack Dam, a few miles downriver. The higher mean pool of the new reservoir necessitated raising the bridge from its original height. A bridge of similar design in Meigs County, Tennessee, that carried Tennessee Highway 58 across the Hiwassee River was imploded in November 2007, along with another similar bridge that carried Highway 58 over the Tennessee River in Roane County.

Hales Bar Dam was a hydroelectric dam once located on the Tennessee River in Marion County, Tennessee, United States. The Chattanooga and Tennessee River Power Company began building the dam on October 17, 1905, and completed it on November 11, 1913, making Hales Bar one of the first major multipurpose dams and one of the first major dams to be built across a navigable channel in the United States. It began operation on November 13, 1913. On August 15, 1939, the Tennessee Valley Authority, which had been established by the President Franklin D. Roosevelt administration to develop and regulate flood control and hydropower in the Valley, assumed control of Hales Bar Dam after purchasing TEPCO's assets through Eminent Domain. It had conducted a lengthy court battle that went all the way to the US Supreme Court. The TVA worked for two decades trying to fix a leakage problem that had plagued Hales Bar since its construction. But, after continued leakage and determining that expanding the dam's navigation lock would be too expensive, TVA decided to replace the dam. It built Nickajack Dam 6 miles (9.7 km) downstream. Hales Bar Dam ceased operation on December 14, 1967.

Raccoon Mountain Caverns is a cave located in Chattanooga, Tennessee in a band of Mississippian Period limestone, part of the Cumberland Plateau. Parts of the cave system was discovered and documented as early as 1853, by 1929 Leo Lambert, a local caver who had recently discovered and opened Ruby Falls expanded the known cave passages. Prior to Lambert's arrival, the property was owned by the Grand Hotel and used as a farm for their restaurant. On hot afternoons, it was said that the farmers would relax in front of several cracks in the rock at the base of the mountain and enjoy the cool air that was blowing out. In 1929, Leo Lambert was invited to explore the source of the air. As an experienced cave explorer, Lambert realized that in order for air to blow out of a crack in limestone rock, there must be a large cave beyond the crack to supply such a volume of air. Lambert enlarged the cracks and was rewarded by discovering several hundred feet of well-decorated cave passage in a cave that was close to U.S. Highway 41. He developed a series of trails, installed electric lights, and opened the cave to the public as "Tennessee Caverns" on June 28, 1931. The original tour, now known as the Lambert Tour, circled the Crystal Palace Room which was believed to be the largest room in the cave. Some twenty years after its opening, the Smith Brothers were managing the cave and discovered a small hole just off the Crystal Palace Room. The opening pinched down to 7.5 inches, so tight that the explorers had to exhale so they could squeeze through the gap. Less than twenty feet later, they found that the passage opened into a larger room and continued their discoveries. Eventually, they were able to enlarge the tour to include these newly discovered areas. Today, this ~0.5 mile loop tour is known as The Crystal Palace Tour. Spelunking tours known as Wild Cave Expeditions, were added in the 1970s, allowing visitors to visit the undeveloped areas of the cave beyond the commercial section. To date, over 5.5 miles of passageway has been discovered and mapped, with new discoveries still being made. Over the years, the name of the cave was changed from Tennessee Caverns to Crystal City Caves to Crystal Caverns and eventually to its current name, Raccoon Mountain Caverns in the late 1970s. Today, the property is also home to a campground with full service RV sites, water and electric sites, primitive tent sites, and cabins. The cave is known for its high level of active speleothem growth, fossils, and resident wildlife. In addition to several salamander species, the cave is home to a unique spider species referred to as the Crystal Caverns Cave Spider (Nesticus furtivus). This species, discovered initially in 1938, and officially described in 1984, is only known to exist within Raccoon Mountain Caverns.Raccoon Mountain Caverns is a major tourist attraction and is one of two caves in the Chattanooga/Hamilton County area that is open to the public.
