Summary |
The scientists-without-laboratories are on top of the world, based high up in the peaks of the Rocky Mountains range in Colorado. This area is rich in history, full of diverse plants and animals and is a geologist's dream. The team has been given its orders - they must take a memento of the mill and send it, by air, along a valley to Kate. Mike and Hermione decide to take a silver-nitrate photograph while Ellen and Jonathan hope to make hydrogen balloons to get the image to her successfully.
