A new scientific tool called a light detection and ranging (LiDAR) survey is making finding lost cities easier. The LiDAR can take pictures of the ground even when it is covered with tons of trees (like the tropical area in the photo).
This laser tool, that is used in a plane to take pictures of the earth, has already helped archeologists in Belize. Now it has been used in a similar way to find the ruins of a famous city in Honduras.
The finding of the lost city of Ubar, which was told in Case Closed by Susan Hughes, used pictures taken by the Challenger shuttle from outer space. Those pictures were of a desert area which is why the pictures worked in finding Ubar. (that was before LiDAR was discovered!)
STEM Challenge: Can you name a lost city? (you can look this up!) Do you have an idea if either of the tools mentioned above would work to find it?
The first girl to answer the STEM Challenge will get a free 6 months of twixing! The winner will be announced on Sunday, June 10.
How fun to know that lost cities are being found! The winner of this STEM challenge, as you can see, is midnightdancer!
Thank you to all the entries:)
You Go Girls!
