The new 'gold' of the Yukon - BBC Travel

IMG_0418-2.jpg

It's been 3 years since I was in the Yukon doing fieldwork, but it was such an amazing experience exploring the wilderness of the Yukon by helicopter and on foot that I had to write about it for BBC Travel. The trip was part of my research when I was a geologist at Harvard University and we were looking for rocks that nobody has ever seen before on mountains that don't even have names as so few people have ever been there. The rocks record a time when the entire planet was covered in ice - known as the Snowball Earth and we wanted to find out how and why that happened and whether life survived.

We may have cracked the mystery of Stonehenge - BBC Travel

After visiting the Preseli Hills in Wales I became fascinated by the mystery of Stonehenge's rocks. Half of them come from these hills in Wales over 260 km away. You can see it when you are there, they look exactly like the rocks that make up parts of Stonehenge, but it baffles the mind as to how they got to the site at Stonehenge. I started to read more about this prehistoric mystery and talking to scientists and I learnt about how much we do and don't know about this monument so I wrote about it for BBC Travel. I am still amazed at Stonehenge and what it may represent, I think there is still a lot that we don't know about this place but scientists are working hard to understand what prehistoric man was up to all those years ago.
