Hanging Bog State Preserve is a 16-acre (6.5 ha) forest that is on the edge of the Cedar River valley in Iowa. It was deeded to The Nature Conservancy in 1968, and it became a state preserve in 1981.The bog has an area that is perennially wet because when water passes through the ground, there is a layer that the water cannot get through, causing the water to surface on a hillside and also form tufa. There are terraces formed by tufa on the lower slopes of the wooded hillsides, which are the namesake of the forest.Skunk cabbage starts to bloom in the forest when there is still snow. There are over 170 species of plants in the forest, as well as 23 species of bryophytes. Spring wildflowers and ferns can be found in the forest. It also contains sugar maple, basswood, and red oak.

The Chain Lakes Bridge is a historic structure located southeast of Palo, Iowa, United States. It carries a pedestrian trail for 370 feet (110 m) over the Cedar River. The Linn County Board of Supervisors began planning for this span in the early 1880s. They appropriated $20,000 for this two-span Pratt through truss The Wrought Iron Bridge Company of Canton, Ohio, which built bridges in the county since 1879, completed this structure in 1884. The bridge was listed on the National Register of Historic Places in 1998. While it was built to carry vehicular traffic, it is now in a nature preserve maintained by the Linn County Conservation Board.

The Taylor–Van Note House, also known as Blairs Ferry Wayside Inn/Vanesther Place, is a historic building located in Cedar Rapids, Iowa, United States. Charles Taylor had this two-story, wood frame, vernacular Greek Revival house built in 1846. The family owned the house until 1888 when it was sold to Lazarus Van Note, whose family owned it as late as 1985. Oral legend has it that Taylor rented the front rooms to travelers as they passed through the region. It was located close to James Blair's ferry across the Cedar River, which is why it has long been known as the Blairs Ferry Wayside Inn. The house was built of heavy timbers and exemplifies a traditional I-house. It features two rooms on both floors across its length, and one room deep. The main door is flanked by sidelights and a transom across the top. The house was listed on the National Register of Historic Places in 1985.

Seminole Valley Farmstead is a collection of historic farm buildings located in Seminole Valley Park on the west side of Cedar Rapids, Iowa, United States. The historic designation includes the farmhouse (c. 1902–1903), summer kitchen, livestock barn, tool shed, ice house, chicken house, and smokehouse. There is also a small orchard and a garden. The complex is located near a bend in the Cedar River. The farm represents a transitional period between Iowa's austere pioneer farms and the mechanized farms that developed later in the 20th century. The nearby timber was a source of raw materials for the farm, the fertile bottomland on which it is located provided rich soil for grazing and cultivation, and the smokehouse and ice house were used to preserve agricultural products for later consumption. At the same time the barn and the chicken house were more substantial than those from earlier times. It was listed on the National Register of Historic Places in 1976.

The Duane Arnold Energy Center (DAEC) was Iowa's only nuclear power plant. It is located on a 500-acre (200 ha) site on the west bank of the Cedar River, two miles (3.2 km) north-northeast of Palo, Iowa, USA, or eight miles (13 km) northwest of Cedar Rapids. DAEC entered operation in February 1975. On August 10, 2020, the plant cooling towers were damaged during a derecho, and repairs were deemed uneconomical, as the plant had already been scheduled for decommissioning in October 2020.The operator and majority owner is NextEra Energy Resources (70%). The Central Iowa Power Cooperative owns 20% and the Corn Belt Power Cooperative owns 10%. In January 2018, NextEra Energy announced that it was unlikely that DAEC would operate beyond 2025. The plant was given a 20-year license extension to 2034 but considered closing after Alliant Energy, which contracts for 70% of the plant's electricity, announced it would instead be buying electricity from subsidized sources such as wind and natural gas. In July 2018 the expected closure date was amended to October 2020. The unit permanently ceased making power on 10 August 2020, due to storm damage from the August 2020 Midwest derecho. An NRC report of the incident stated that "the vacuum drawn in secondary containment by the standby gas treatment system was slightly below the technical specification (TS) limit", indicating that the secondary containment system might not have been fully effective had it been challenged. Thus the incident was considered by nuclear safety experts to be "a close call".
