The unpaved county road following the westernmost ridge line south from the King Range crosses Usal Creek near the Pacific coast, but the bridge may be removed during winter months.

Usal Creek drains a valley between two ridges of the California Coast Ranges.

The main creek flows southwesterly from the confluence through a gap in the coastal ridge.

In 1896, Dollar purchased the steamship Newsboy to transport lumber from Usal to San Francisco.

A fire in 1902 destroyed the sawmill, a warehouse, a school house, and the county bridge over Usal Creek.
