I know this is a common shot from Yellowstone, but there's a reason. This spring is approximately 300 feet across, so you can't get a good view of it from the boardwalk. You have to scramble up a hill a little ways to really see its beauty.
The Yellowstone trip was incredible. We saw every animal that we wanted to see, although we had to go to the Grizzly & Wolf Discovery Center in West Yellowstone to see those two. If you haven't been, take any opportunity you have to get there. It's a place like no other.
Also, the hike up Mt. Washburn was, hands down, the best hike ever. EVER. If you go to Yellowstone, you have to do it.
This is a picture from my cruise to Alaska earlier this year. This shot was from the back of a horse, which is a lot harder than you might think. It's a lot harder than I thought it would be before I tried it. =) Emerald Lake is a gorgeous green lake in the Yukon.
