UHhhh its a GLACIER in a TROPICAL CLIMATE>.. did you really think it wasn't going to melt? Glaciers expand and contract ALL THE TIME... its been 10,000+ years since the last ice age, why would anyone expect a glacier in a tropical area, even at the top of a mountain, not to melt away?
Doesn't take a rocket scientist to figure out that a glacier doesn't stand an ice cube's chance in hell if it's located in a tropical zone...
