“The Rocks Are Burning” is a 17-page Kirby story from CAPTAIN AMERICA #197 , inked by Frank Giacoia, lettered by John Costanza and coloured by Phil Rachelson. Kirby returned to his 1940s creation in the 1970s with the 8-part “Madbomb” story which concluded in #200 (which conveniently came out right around the US Bicentennial) , so this is in the middle of that story.
After the conclusion of the “Kill-Derby” battle of the previous issue, this story has Cap and the Falcon battling in the underground lair of the New Society in their search for the “Big Daddy” Madbomb.
While they fight inside, General Argyle Fist leads his US Army squad looking for the enemy in the desert above. This is a bit of a placeholder issue, though it reads well as part of the overall 8-part story, with a lot of action and one of those great big Kirby devices in the form of a sonic gun. I also like the General, who has some funny overblown dialogue in these issues.
