 And that was at the end of what's called the Little Ice Age, when there was a lot more precipitation. And I'm sure Lake Bonneville was at a higher stand at that time, too. So it may have had an effect then, but it didn't seem to have much of an effect this time. There was about a five-magnitude quake out by the airport there in 1982 in, I think, September. And that may be all that the maximum stress is.
