Comments:
Cut two fast running and wide propagating slides with ski cuts on steep rollovers in the phantom trees, as well as a big wet loose growler on the top of the waterfall. broke 6-14 inches deep and ran on a layer a couple inches above the crust in all cases. Was quite touchy and things we're moving very fast on that layer and propagating over 100 feet wide in one case.
