While volunteering at a University, through a work exchange in Terengganu, Malaysia, I got to meet and accompany a Geology professor on some sampling missions.
He was trying to prove that the sea level was several meters higher 4000-6000 years ago by finding remains of mollusks caked onto the rock at higher then current levels.
Getting to explore the islands of Terengganu was an awesome experience.
Bouldering, snorkeling (I saw my first shark snorkeling here) exploring nesting islands and bat filled caves, it was all so cool.
Unfortunately, my camera died along the way, but I got some cool shots of my experience.
Bidong, a former refugee island, was the only island with traces of former inhabitants.
