While in Utah, Kim and I bought a little book called "Best Easy Day Hikes Salt Lake City", and we picked a hike near Alta because Kim wanted to see that area in the summer. We ended up taking the "Sugarloaf Road" hike, which was the hardest one in the book.
You can check out our hike mapped on mapper.acme.com, mapped on the GMaps Pedometer (includes distance and elevation), and direct lat/lon links to the starting point, first ski-lift peak, second ski-lift peak, and Secret Lake.
As you can see on the GMaps map, despite having a guidebook we had no idea where we were going at first, and had to double back. Kim didn't mind because she is mostly bionic, but pretty much every step of this hike kicked my butt. It was an awesome hike though, with tons of fresh air and amazing views, and barely another person.
The total distance was about 6 miles, and the elevation gain was 1200 feet (low was 9300', high was 10,500').
And I forgot to adjust my camera's clock for Utah time, so the timestamps in the EXIF data are off by +1 hour. These were actually taken from ~noon to ~4 PM.
