English - Tikal was discovered and explored during a very successful expedition led by Profs. Kramer and Kiesling. A decade later, a scroll is found that hints of a lost temple near the first site. This rumor rekindles their passion for Tikal and the two scientists start to discuss the prospect of another expedition to Central America.
