The Balder is an English river that rises on the eastern slope of Stainmore Common in the Pennine Chain and flows eastwards for about 13 miles (21 km) to the River Tees at Cotherstone.

The River Balder is in County Durham. The head of the valley is a bleak moorland, with hills around it exceeding 500 m (1640 ft).

The River Balder enters Balderhead Reservoir about 7 km from the source, at around 330 m (1080 ft). It spills into two more reservoirs further down Baldersdale: Blackton Reservoir and Hury Reservoir.

Ultra do Céu is a 42 miles crossing in the rural area of Minas Gerais, connecting the city of Ibertioga to the Ibitipoca State Park.

The route starts on the dirt road, with a small stretch of asphalt arriving in the city of Santa Rita de Ibitipoca. 

The Herring Road is thought to have been predominantly in use during the 18th and 19th centuries when the herring industry was strong, although records of the inland trade in fish go back to the mid-17th century. The route was used by people bringing home a stock of salted herring for winter use and also by fishwives carrying huge creels of herring from Dunbar to the markets in Lauder. There are parts of the route where V-shaped gouges may be evidence of the repeated use of heavily laden carts or packhorses, perhaps trying to get through the mud.
