NOVA: "MAKING NORTH AMERICA"
PBS, 9:00 p.m. ET
Part 1 of 3. You gotta lava show like this. It’s a geological big-picture history of our continent, explaining how volcanic eruptions created the land on which we live, how different land masses broke apart, and how continual tectonic shifts change our landscape dramatically – even though it’s too slow for us to notice. Yet here it is, told in three interlocking, interesting parts. For a full review, see David Hinckley’s All Along the Watchtower. Check local listings.
