Thanks to CMDR’ Deadfight and Frostfall for tipping me of to this location.
This is certainly way up there in my favourite places for volcanic geysers so far. The view of the ELW is stunning when the orbital period is just right. When daylight hits the canyon, the volcanic geysers erupt much more frequently and create a huge cloud of vapor that almost blocks out the sun.
