Mt Lawaluk

This small, lava-capped mesa (flat-topped hill) has been described as a circular lava disc with steep rocky sides. There is a shallow basin on the top and prominent cliffed basalt outcrop on the north and north-east side. Ollier (1967a, 1969) cited this as an example of a lava disc, an unusual eruption whereby a single sheet of lava swells in a bulbous form from a vent - the congealed skin containing a more fluid interior - and then collapses or deflates to spread radially as a flattened or concave disc.
