Marine Life Impression on Cave Wall
Litekyan / Ritidian
There are signs in many places on Guam that remind us that much of the island was once below sea water many years ago.
How else would signs of marine life be found in impressions left on cave walls, like this one in Litekyan (Ritidian)?
A million years ago plus, Guam was rising and sinking. Each movement modified the terrain in different ways. Imagine! At one time Matåguak and Mount Santa Rosa in Yigo were like little islands, completely surrounded by the ocean.
Like the history of the people, the island itself has had its ups and downs.
