We certainly were not prepared to go to the top, but these guys were. Check out their gear.
And they're off!
We watched their progress throughout the day. The arrow below is pointing to some tiny specks on the mountain. Those are climbers.

My friend, Roger, has a really nice telephoto lens. He let me use his picture so you could get a closer look. Thank you Roger.
Dinner time discussion: Why would someone risk their life to climb Mount Rainier? How do you think a climber would prepare?
