What American city is also the site of one of the largest salt deposits in the world?
Because I didn't say major American city or the largest salt deposit both Detroit and Hutchinson are correct answers. For the record, Hutchinson has the largest salt deposit in the US, however Detroit's is pretty large too, some estimates suggest that there is enough salt in the Metro Detroit underground to last 70 million years--and that's a lot of salt! Here's a link to a great map of major salt deposits in North America.
Congratulations to Amy, Shane and Andrew you have each won a copy of The Seasoning of a Chef.
