L10S5 The Rainforest's Hidden Cities (Inferences)

It takes years to collect the equipment needed for a search.

The region is difficult to explore.

Archaeologist must make a map of the area.

The Maya buried structures deep inside the thick forest.

"...The Maya, the people who built these structures."

"Yet no one knows for sure why their empire didn't last."

"The remains of these cities may give clues."

"...poisonous snakes, swarms of bees, and hot, moist air."

"attached to the bottom of the helicopter"

"quick, powerful rays of lights"

"narrow enough to pass through openings"

"the shape of the ground"

Locating Mayan ruins benefited both groups, helping one to preserve the ruins and the other to study it.

Both groups wanted to explore the natural landscape of the rainforest.

One team mapped half of the structures they found, while the other team mapped the other half.

Neither group wanted special events to celebrate the work they did.

An archeologist studied a LiDAR map to prove that 27 shapes in the forest were natural parts of the landscape.

The 27 large structures discovered on a LiDAR map proved that the forest was easy to travel through.

A LiDAR map showed that 27 structures on the ground were probably platforms for Mayan events.

The forest was not very thick, so a LiDAR map was easily able to show 27 large shapes.

The ruins of ancient cities stretch across the forest floor.

The poisonous snakes

They didn't expect to find more than 61,000 Mayan structures.

The Mayans probably used the low platforms for special events.
