In April, planes flying over the ancient Maya city of Caracol used laser technology to look beneath the rainforest and see the remains of the city. The equipment, called Light Detection and Ranging (LiDAR), bounces lasers off the ground to construct 3-D maps.
The new map shows that the ancient city was much larger than previously thought. It had been impossible to see the majority of the site because of the dense rainforest covering it.
