Caves in Guyana

Are there any caves in Guyana? Very few it seems which is not too surprising given the lack of suitable geology.

There is one cave under Kaieteur Falls.

There are also a few caves in the Roraima area (see picture) including one called the Oil Bird Cave. I am not sure if all these are in Guyana.

Note: there seems to be several caves called Oil Bird Cave. Oil Birds live in colonies in caves in this part of the world.

Education on the rise world-wide

Some really good news - many more people around the world are getting a better education now than previously. According to a recent report:

"More than 61 percent of individuals 15 or older—just over 3 billion people—finished at least some secondary school during their lifetimes as of 2010. This proportion has risen from 36 percent in 1970 and from 50 percent in 1990."

This is supported by figures for enrolment in primary education from the UN. It seems to me that this is very encouraging trend which has huge and very positive implications. Yet the media seems not to be talking about it. Their focus needs to cover both positive and negative ...

Tremor

Felt a slight tremor this morning around 4.40am. Had I not chanced to be awake I would never have noticed it. A few objects on shelves rattled briefly.
On checking the cause seems to have been an moderate earthquake off Venezuela.
