Howlite was first discovered in Nova Scotia in 1868 by Henry How, a chemist and geologist.
Howlite is most commonly found in irregular nodules, sometimes resembling a cauliflower. The nodules are white with fine grey or black veins in an erratic, often web-like pattern, opaque with a sub-vitreous luster. Howlite has a Mohs hardness of 3.5.
