The Dix slides are on my list too, many to be had. Apparently the slides on Dix are some of the first to come in.
I took a stab at the Eagle Slide weeks ago, far too much water made the approach almost impossible we bushwacked for 2 hours at one point and progessed little more than .5 miles. I was hoping to get on the slide and have to deal with some mixed roped scrambling...good fun and a lesson learned.
The person in this pic was leading the pitch, he made for a nice subject.
