    Salt Mining a Serious, Sometimes Dangerous Business

    Salt lingers in the air, and miners swear it does wonders for their sinuses. "I've always considered it coming down to a health spa every day," miner John Goho said with a smile. But salt mining is a serious, sometimes dangerous business, practd in this western New York countryside since the days of mules and pickaxes more than a century ago.

    Salt domes are considered to be ideal for storage because: While underground caverns may not seem like the best place to store an emergency oil supply, they're actually very secure. For one thing, since they're 2,000 to 4,000 feet (610 to 1,219 meters) underground, the extreme pressure prevents cracks from forming and leading to leaks [source

    Salt Production and Processing - Morton Salt

    Salt may appear in veins, as does coal. Veins are the original bedded salt deposits. Salt also may be found in domes, which were formed when Earth pressures forced salt up through cracks in the bedrock from depths as great as 30,000 or 40,000 feet; they resemble plugs of almost-circular shape a few hundred yards to a mile across.
