The lake was overfull because of this year's rain. The bottom of the stairs were underwater...

Is the lake's origin volcanic? Or was it formed by an impact? Nobody knows.

The first years decided to play capture the flag, girls vs. boys. Here Eileen and Kelly defend their flag. The girls had a great strategy and won the first game.

The next day we head to Meteor Crater.

These red rocks we drove past are part of the Moenkopi Formation, which were the uppermost layer of rock when the impact occurred.

... and Jay regales us with stories about the crater.

Hey, look! Boulders!

Jay explains how we can observe the crater's overturned flap of rock by looking for crossbeding in the Moenkopi sandstone.

We walked about a quarter of the way around the rim.

The white stuff is the Kaibab formation, the rock layer that was laid down below the Moenkopi, but here has been flipped on top by the overturned flap.

The only vehicle mishap involved Brian's vehicle sliding into a snow bank. A couple of pieces of wood behind the back tires, less than five minutes, and we were on our way.

The enterance to the tube had a wall of ice on one side, and the rocks were also slick with ice.
