Update: Best hike within an hour or so of Park City?

[Wasatch Rebel]

My friend from New Jersey will be staying at Park City. He wants about an eight hour hike. The last time I took him hiking, we made it up to Emerald Lake on Timp. He was real tired when we got back down. I don't want to wear him out too much, but let him see some beauty and give him a pretty decent hike as well. Now that I know he's in Park City, that opens up the Uintas as well as the Wasatch, so, do you have any further recommendations with that in mind, and the 8 hour round trip?

Thanks,

Shane
