Cameron is at 10276 and accumulates a lot of snow since it's in the north. I've seen two moose there and have heard others tell me they've seen moose. Some of the highest passes are 12000 like Independence. Monarch is 11300, Rocky Mountain Natl Park has 12108 but that's not a high-volume US highway for shipping and commerce. Berthoud pass is at 11300 on US 40, a main commerce road. If you've got a well-built SUV, and a lot of experience, you can drive an old mining road nearly all the way to Mt. Antero where the road stops at 13800. Then I-70 and US-6 almost go in the same spot but I-70 tunnels through Loveland Mountain (not to be confused with Loveland city.) If you like weather observations from METARS, K0CO (yes, that's right, mixed numbers and letters) is above Berthoud pass and pretty much just has a freezing blizzard all the time.
