I don't know enouph about Mitten Ridge except that most of it's points are nasty climbs. If I did alot of hiking in that area I would have added it. Being in Colorado I don't have the chance anymore to check that area out.
I think I've been down Casner Canyon, it thats the one that starts at the fish hatchery. I did it about 15 years ago so I don't remember it much. We hiked up Schnebly hill road and down Casner Canyon.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
