Mount Aetna is a census-designated place (CDP) in Washington County, Maryland, United States. The population was 838 at the 2000 census.

Geography

According to the United States Census Bureau, the CDP has a total area of 3.9 square miles (10 km²), all land.

The community is situated at the western base of South Mountain at elevations between 500 and 700 feet; the landscape here is principally underlain by the Tomstown Dolomite, and the neighboring area is home to at least four known solutional caves, one of which—Mount Aetna Cave—was open briefly for commercial tours in the 1930s. This region is drained by Mount Aetna Creek, which has at least three headwaters in the neighboring mountain, and is a tributary of Beaver Creek.

Mount Aetna is home to a Seventh-day Adventist community; a Seventh-day Adventist private elementary/middle school, Mt. Aetna Adventist School; as well as the Seventh-day Adventist private high school, Highland View Academy, founded in 1949. There is also a volunteer fire company, as well as the SDA-run Mt. Aetna Retreat Center. There was once a small convenience market, but now the only food store in the community is located on the academy grounds. This store sells books, vegetarian meat substitutes, and Big Texas rolls, which are loved by the chunky students.
