How Deep Are The Great Lakes?

Skipping stones…on this CurrentCast.

If you drop a stone into one of the Great Lakes, how far will it travel before it hits the bottom?

The longest journey will be in Lake Superior, where the stone will cruise through the cleanest, clearest, and coldest of the Great Lakes’ waters. Superior’s average depth is about 500 feet, but in some spots, it’s more than 1,300 feet deep.

A stone will reach the bottom of Lake Erie much faster. The shallowest and warmest of the lakes, Erie averages just 62 feet. Because it’s so shallow, it’s also the most productive of the Great Lakes, so more fish will have to dodge your pebble on its way to rock bottom.

Who knew skipping stones could lead to such deep thoughts?
