Our data argue that the mantle just accumulates down there until some critical moment when it becomes unstable and drops off.

When I first showed this data to others, they had a hard time believing that mountains could pop up so quickly.

These results really change the paradigm of understanding of how mountain belts grow. We've always assumed that the folding and faulting in the upper crust produced high elevation mountains. Now we have data on ancient mountain elevation that shows something else is responsible for the mountains' uplift.

Brett is like he is because of his pace. If he drops back he becomes easier to hit so we addressed that last night. It's a confidence thing and about understanding the way he has to bowl. We've addressed these issues quite a few times with Brett, we did it with his one-day bowling a few years ago, and hopefully today is a step in right direction.

Each one of those drops becomes an impassable barrier for fish,

When we argue for our limitations, we get to keep them.
