So I feel reasonably competent backpacking in forests. I'm planning a 100+ mile hike in Utah in 2017(this summer is full). This hike will spend most of it's time above 10000ft above treeline. I'm looking for any useful advice. I already know to get over passes early in the day before thunderstorms build up. Oh this will be probably Aug/Sept time frame. Is there anything particular that I'm missing being a woods hiker versus high alpine?
