Mirror Lake Highway isn't being maintained, but Wolf Creek Pass is open. However, just cause you can see it from the road doesn't necessarily mean it's safe.
This storm is a good news, bad news kinda storm. The good news is... all the new snow will finally kick winter into gear and get the season rolling. The bad news... all the storm snow is resting on a weak, sugary mess near the ground. Here's the deal- your choices for riding or turning are limited to mid and high elevation snow facing the north half of the compass and that's exactly the type of terrain where you could trigger an avalanche today. Underneath yesterday's storm is early season snow that grew weak and sugary and recent winds drifted snow everywhere. Complicating matters... the snow will feel strong and supportable. So we've gotta think not only about the snow we're riding in, but also the snow we're riding on.
Unfortunately, a lot of avalanche accidents and close calls occur early in the season when we don't think there's enough snow to slide. Right now we've got a dangerous early season setup- strong snow on weak snow. Today, you'll want to look for and avoid any fat, rounded piece of snow, especially if it sounds hollow like a drum. Remember- clues like shooting cracks and booming collapses or whoomphing sounds are huge clues to unstable snow.
There's not much snow and triggering a slide will immediately ruin your day, taking you for a nasty ride through rocks and stumps barely hidden underneath the shallow snowpack, resulting in a season ending injury.
