The trail was snow free until headlee pass, where parts of the switchbacks were covered in snow. Getting past the snow was not difficult. I had an ice ax ready to go, but didn't need it since enough of the trail was snow free. After reaching the top of the pass, I traversed toward the lake where I came upon a small snow bridge. I probed a bit and it seemed ok. There were obvious boot prints across the snow, so stepped up, walked a couple steps, and then fell right through. Fortunately, I was ok, just fell up to my thighs or so. A great learning lesson for me, considering I'm still learning a few things. I then proceeded further toward the lake where the whole basin was covered in snow. I would have needed to cross a gushing, snow covered creek, which looked risky. I realized I was out of time, due to my late start and decided to play it safe and turn back, considering I was the only soul up there. Overall, this was an incredible and fairly challenging hike. I plan to head up again in a few weeks, much earlier and get to the top. Wirtz basin was gorgeous, despite the amount of loose rock needed to hike on.
