We destroyed ourselves doing a 14 miler on mixed snow/ice in the Lost Creek Wilderness (CO). Yikes, toughest 14 miles I've done in a while, constantly switching foot gear from hiking shoes to microspikes to snowshoes, back to spikes, back to snowshoes, at least a dozen changes total, a one mile section took over an hour each way, swimming in old wet snow, fun stuff! The good news is we didn't see a soul, not one person, though we did see one pitched tent. AND we didn't even leave our own county to do this.
