"Maria Reiche wanted to put her curious mind to the test. When visiting Peru in 1941, she trekked across the land and discovered hidden lines covered in centuries of clay and sand. Fascinated, she picked up a broom from her tools and began sweeping for miles and miles to uncover more details, taking time to track her movement and sketch out the precise shapes she followed. Her first discovery was a spider-shaped carving spanning hundreds of feet of desert! Sweeping her way across the land, other shapes followed-a monkey, a condor, and a whale. But in the midst of these discoveries, she found out the land was going to be used for farming. She got to work again, this time demanding a press conference to announce her discoveries and stop the destruction of these ancient works of art-and it worked! Her efforts protected the land, which was later named a UNESCO World Heritage Site in 1994 thanks to Maria's tireless efforts."--
