Pyramid Ridge is a 3,520–3,560 feet (1,070–1,090 m) mountain in Mendocino County, California.

It has isolation of 6.21 miles (9.99 km) from Cow Mountain Ridge to the north.

18 plots ranging from 3–10 acres (1.2–4.0 ha) in size were selected that contained knobcone pines that were dying off for an unknown reason.

The California Department of Forestry and Fire Protection was responsible for all the burning.

As of 2016 informally developed trails led from the southeast, southwest and west segments of that trail, which were to be closed, barricaded and restored to a natural state to deter trespass on private property.
