On December 15, 1977, the seal of Garrett County went into effect by virtue of Resolution #7. The seal is elliptical, with the name "Garrett County" inscribed above the upper fourth of the ellipse, and "Maryland 1872" inscribed below the lower fourth of the ellipse. The date "1872" depicts the year of the formation of Garrett County. The seal illustrates a large snowflake to depict winter; water to represent sailing; and oaks and conifer to represent the county's mountains. The colors are peacock blue for the sky and water. The blue and white background is divided by kelly green.
