We headed out at 5am for the 2 hour drive to the National Park. On the way we ran into some dense fog and as we got closer to the park we ran into some freezing fog and icy roads. We arrived at the park at 7am and were not surprisingly the only ones there. Everything was coated in rime ice.
We hit the 8700' summit (5 miles) in 1:40 and spent 6 minutes getting a few pictures before heading back down. The run down took 1:29 and the slightly warmer temperatures made it a bit easier. In all it took us 3:15:02 for the 10 mile round trip (and another 1:21:38 for the 3 miles prior to that).
