Mr. Grondine,

You lost me there in that email and I'd appreciate some
clarification. Specifically -

I'm certain no one believes that there is currently any lava on the martian
surface, just the rocky remnants (weathered basalt in my opinion but that's
a horse of another color). Are you saying that lava flows *never* existed
on Mars?

Thanks for any clarification you can provide.
