What does lava smell like?

How is it supposed to smell?

It's tough to remember smells, much less describe them, but growing up in Hawaii I've smelled lava several times.  It doesn't have a really strong odor on its own, it's like ... well, hot rocks.  A bit like hot metal, say a soldering iron or a hot stove, a bit like regular stone, say a pile of dry gravel or concrete mix.

Sometimes, especially right near the vent, there's sulfur gases mixed into the lava, in which case there's a strong sulfur smell, like overcooked hard-boiled eggs.  But most of the time I've been near a lava flow, it's just a clean hot stone smell.
