Lots of diverse movements for a 5.8 route. It is a lot of fun. There is some slabby stuff, some off balance stemming, and plenty more. It is heavily bolted, especially for the first half of the route. There are 2 anchors to choose from...the spray painted ones basically along the bolt line and the shiny new ones off the bolt line more up the crack line that would take a serious traverse to get to on lead. I used the anchors on the bolt line. If you follow the bolt line, the rock quality is good and clean...if you follow the crack after it diverges from the bolt line, it gets a little chossy.
After four days of cleaning and trundling loose blocks and choss, Mystic River was calling my name. The FA went quickly and smoothly at the end of a long day of brushing and sweeping. An excellent route, if I say so myself. :-)
