Mountain range or saw-toothed
A modern spelling variation of the Spanish word 'sierra', which literally translates to 'saw' and refers to the jagged peaks of a mountain range. It gained popularity in the United States during the late 20th century, often associated with the Sierra Nevada mountains. This specific spelling adds a final 'h' for a more unique, decorative appearance.
