The post office was located in a small shack near the railroad trestle over Shavers Fork of Cheat River

 

The Spruce Post Office was established in 1898. The post office was located in a small shack near the railroad trestle over Shavers Fork of Cheat River. The post office was named after the Spruce Mountain, which is located nearby.

The Spruce Post Office was discontinued in 1954. The post office was closed due to declining mail volume. The shack that housed the post office was eventually torn down.

The only remaining evidence of the Spruce Post Office is a large boulder that is located near the railroad trestle. The boulder is chiseled with a square, and it is marked with the following information:

• U. S. 3,738.1 B. M.

The boulder is a U.S. Geological Survey benchmark. A benchmark is a permanent marker that is used to establish a reference point for surveying. The benchmark on the boulder is used to measure the elevation of the land around it.
