This is a great subject and one thing I've learned is you never stop learning in the mountains. Weather can be fickle and routes can get lost in clouds that come from nowhere. Cell phones often won't work in our mountains. An InReach satellite texting device is good to have even just to let people know your alright. Two hiking poles and a 8'x12' tarp can make an instant shelter with a couple bungee cords and some parachute cord. Always be prepared to hunker down and spend the night. Doesn't take much to be dry and comfortable. A cheap foam pad will keep the ground from sucking all the heat out of you, even just sitting on the ground and weighs next to nothing.
