I think its a volcanic vent. It didnt build up a volcanic mountain.
The vent generated a large lava lake. Why ? well the edge of the lava sets cold and the spatter at the edge generates a wall , taller than the lava lake. so then the lake can become a bit deeper.. so it can create the wall a bit taller.
Its a vent that has restarted and repeated making smaller structures inside the larger older lava lake structure.
The lake has overflowed. There are two lava channel structures. The banks of the the lava river form walls, for the same reason the lake is walled. These walls are distinctive. They are not the curves of impact crates or folds of bedrock structures. they are rather featured, a bulge or valley has its own bulged and valleys in it, its fractalic. this is caused by randomness of lava flows.
there's two lava channels, one going north, one to the north west.
Where the river of lava formed a lava field, a plain covered in lava, we don't see the smaller and smaller lava channels of various branches, its just a plain of sand now, as erosion has resulted in the smaller rock features being eroded away or covered over.
Compare to Leilani estate 's vent off Kilauea , Island called Hawaii, Hawaii starting May 2018. vent with a little mini lava lake, lava channel flow, branchings, then a lava field.
