Ferrobutte is a geological name describing the unique landscape given to the post office established in 1900 at Roger’s Station. The name is derived from Ferro “iron” and Butte “isolated hill with steep, often vertical sides and a small relatively flat top”. The terrain at Roger’s Station includes such a “butte” on land that once had significant iron deposits. The post office closed in 1915.
