Splitrock is an abandoned townsite in Beaver Bay Township, Lake County, Minnesota, United States; located at the mouth of the Split Rock River.

About 350 men worked in the Split Rock River valley felling red and white pine.

The lumber company controlled the town's harbor, railroad, coal dock, and store (which included a post office).

The company built a railroad 10 miles (16 km) long to carry cut logs down to the river mouth, where they were dumped into the water from a trestle platform.

[3] The logs were sluiced from a dammed area at the river mouth into the lake, where they were rounded up into rafts and towed to a sawmill in Duluth by the company's tugboat Gladiator.
