Almost wrote this in as a dual with Plate but I only saw the one burst out of Slot. It did finally allow me to understand the spatial relationship between Plate, Slot, and Sponge. Would have been a great screen shot if I'd acted a little faster! |

(wc) Slot's activity since late December has gradually carved out a broad crater with steep walls in the larger Sponge mound area. The crater floor is just a tad higher than its vent, again separated by a steep wall. It was non-existent prior to this. |
