No water is available in this portion of the traverse, so make sure you have some leaving Grays Peak.
After getting to Mt. Edwards, the ridge somewhat opens up and makes its way to Argentine Peak. This is a broad rolling summit and hardly noticeable as just another bump on your ridge traverse. At the top, you'll see your last major ascent of the day, to the top of Square Top Peak.
While this portion of trail might be a bit less exposed than some of the other trails that you've been on during the course of the Loveland Pass to Guanella Pass
traverse, this trail is still fairly strenuous. There are two major ascents, and the descent between the two high points can be steep.
