Sometimes skins aren't enough to get up steeper sections. In this photo, I am climbing Snow Lion couloir. I have metal spikes on my ski boots called crampons that allow me to kick into the hardened spring snow. Also, there is a whippet ski pole in my right hand to stop myself if I slide down the mountain (not visible in the photo unfortunately). This is similar to an ice axe but combines with the ski pole for ease of use. For more information, you can read about the self-arrest mountaineering technique.
Snow stability: In Colorado and many other areas with contenental snow packs, this kind of slope presents a high risk of avalanche for most of the year. However, prediction of avalanche danger becomes more reliable in the spring when the snow melts and sticks together more (known as isothermalization). However, one must always be aware of other factors affecting the snow such as the temperature the night before, rain fall, time of day, and more.
As always, seek proper in-person training before attempting this kind of thing. This post is simply to satisfy curiosity and drive discussion.
