Chapter 1The warm crack

Out on the ice, everything was white and silent, so Zuri noticed the steam straight away: a thin, warm plume rising from a crack no wider than a door.
Professor Lund lowered a thermometer into it and frowned at the reading. “Twenty degrees,” she said. “That isn’t possible. Not here.”
With ropes, helmets and a great deal of care, the team climbed down. At the bottom, the crack opened into a valley the size of a cathedral, roofed with glowing ice.
Warm springs bubbled between ferns taller than a person. And in the rock walls, everywhere they looked, were fossils: spiral shells, long-necked skeletons, leaves pressed flat for millions of years.
“Nobody has ever seen this,” whispered Kit, the team’s young geologist. The question hung in the warm air: what should they do first?

Reading it together
The Valley Under the Ice is a discovery story at Litsee’s reading level for age 10. Its choices have no single right answer: each weighs the excitement of sharing a discovery against the need to protect something fragile, which makes it a strong story to discuss.
Each part has a real fact card about dinosaurs and fossil hunting from the Litsee app’s fact bank, including Mary Anning, the fossil hunter of Lyme Regis.
Talk about real places that are protected so that people can study and enjoy them without damaging them, such as nature reserves or World Heritage Sites.
