Hecla,(hěk'lah,) a conical volcanic mountain of Iceland, situated about 20 m. inland from the S. coast of the island, in a region the very picture of desolation. Its height is 5,110 ft., and the depth of its principal crater abt. 100 ft. Its summit is crowned with perpetual snow, and of its many recorded eruptions, those of 1783 and 1845-6 appear to have been the most appalling in their effects. [s. 445]
