I've heard the Paramount mountain was modeled after Ben Lomond of Utah. But I agree there is a strong resemblance here, though the Paramount mountain looks to be lacking all that wicked choss.
"Legend has it that the mountain is based on a doodle made by W. W. Hodkinson during a meeting with Adolph Zukor. It is said to be based on the memories of his childhood in Utah. Some claim that Utah's Ben Lomond is the mountain Hodkinson doodled, and that Peru's Artesonraju is the mountain in the live-action logo."
