An alternative or archaic spelling of crevasse; a deep crack or fissure, especially in a glacier or ice sheet.
Variant spelling of crevasse, from French 'crevasser' meaning to crack or split. The '-ss' spelling appears in older English texts before standardization to '-sse' occurred.
This older spelling shows how English hasn't always agreed on how to spell borrowed French words—'crevass' and 'crevasse' were used interchangeably until spelling became standardized in the 19th century.
