Ash Updraft

The Burning Ship map z -> (|Re z| + i|Im z|)^2 + c iterated over the parameter plane, framed on a single plume off the north-east flank of the main body so it stands as a column on the Im c = 0 waterline. Three fields carry the colour. The amber filigree is the exterior distance estimate, the ash is a minimum-|z| orbit trap, and the updraft streamers are a windowed |Im z| trap lit on a dark ground.
