The Lost Treasure of the Grand Canyon

Set in the Grand Canyon, a team of Smithsonian researchers have stumbled across a lost walled Aztec city guarded by some evil spirits, including a "great flying serpent of death." As days turn to weeks, Susan Jordan, the daughter of the professor leading the expedition, assembles a team to rescue her father and his colleagues from the clutches of the ancient Aztec warriors and their horrible serpent god.

The Lost Treasure of the Grand Canyon is a 2008 adventure sci-fi horror film set in the Grand Canyon. The movie was due to be released in late November 2008 but the date was pushed back to December 20, 2008, due to unfinished filming.
