Both Engineer and Cinnamon Passes basically go from the area around Animas Forks over to Lake City. You should look them up on a map so you know what we're talking about here.This is my first summit and I have a question about trails. I would like to take the Engineer and Cinnamon passes different days. On the summit site it say to sign up for the Alpine Loop if you wanted to do one of those passes. I signed up for the Alpine Loop on Thur and Fri with the intention of breaking it up. Is my logic correct or what is the proper way to go about this? Thank you in advance for the help.
