Pine C.

 Starting the day out with a chilly 52 degrees knowing we will be swimming in water that never sees the sun.

 The Cathedral Room. The lighting is so bad in here so the pictures don't do it justice.

 Sam and Jacob trying to avoid a swim. This was the coldest I've ever been in my life. We know what hypothermia feels like now.

 Out of the water but feeling the cool canyon breeze.
