Sustained, with 2 particularly difficult sections. A lot of the moves get a lot better once you figure out the technique. First 3 or 4 bolts are easy, then you set off into the overhang with only moderate rests until the anchors. Great fun, but a tricky if safe lead for the grade due to the overhang.
If you go the far left side of Scorched Earth, this is the 4th from last route. It's 3 routes right of Dirty Harry (5.10b) and just right of a short route, not sure of the name.
12 bolts, 2 anchors.
