One afternoon as Mataquana, the chief of Tumon Village, was strolling along the beach, he heard one of his villagers say that a chief named Gadao of Inarajan Village, located in the southern end of the island, was the strongest chief on Guam. Hearing this, Mataquana would not rest until he discovered for himself whether or not he was the strongest.
The next morning Mataquana started out for Inarajan to find Gadao. After many miles he came upon a small hut surrounded by papayas and bananas. He stopped to ask the owner where he could find Gadao, the strong chief of Inarajan. The owner of the hut asked why he was looking for the chief. Mataquana explained his position and expressed his desire to prove once and for all who was the strongest chief of Guam.
The owner of the small hut looked at Mataquana in surprise. Mataquana didn't know he was asking Gadao, the man he was looking for. Gadao then said that he would take him to the chief, but first, he must eat and drink. As Mataquana rested, Gadao shook a very large coconut tree and a coconut fell. Gadao took the coconut and squeezed it until the milk filled a large bowl. He then took another coconut and cut it in half with one blow of his little finger.
Mataquana, seeing how strong this man was, thought that this man's chief would be much stronger. He was afraid that Chief Gadao may have some magic spell or super-natural strength protecting him. Mataquana asked the man if he would show him the way back to Tumon. He is now afraid of meeting Hadao. He took Mataquana back to his canoe and headed for Tumon. Tumon's chief paddled one way. Inarajan's chief, Gadao, paddled the other. With a great roar the canoe split in half.
Gadao's half of the canoe hit the reef of Asgadsa Bay. It was later called Asgadsa Island. Mataquana's half hurled into the ocean north of Guam, forming an island named Rota.
Even to this day the villagers, discussing past events, can't agree as to who ws the stronger chief, Mataquana or Gadao!
