This was an overnight, 7 mile ski tour / backpacking trip in Crater Lake National Park. In the winter, before anything is plowed, you can only enter at the southern entrance. You have to park at the visitor center if staying overnight, and then hike / snowshoe / skin up to the rim. I skinned up to the top, kept going until I was far enough away from any roads, then set up camp. Unfortunately the lake was socked in pretty much the entire time after I set up camp. Despite 3-5 inches of snow overnight, the skiing wasn't that great getting back to the car either.
