On Sunday while Nano, Antje and I were collecting some samples of grey mudstone, Cecilia and Khaled went to explore around the other side of the hill. They found a wall of crumbly sandstone that had been cut to make room for a driveway. Khaled scraped away some of the grime covering the surface and what he found was amazing: bright orange sandstone with mudstone layers – it looked like tiger stripes!
But even more exciting was a diagonal band with broken up pieces of the mudstone that cuts straight through the flat layers – this might have been caused by violent shaking in an ancient earthquake!
We took lots of measurements, collected samples and took many, many photos so we can try to understand how an earthquake causes this kind of damage. Cecilia and Khaled will be heading to southern Bangladesh tomorrow to continue looking for damage caused by ancient earthquakes. We’ll miss them, but can’t wait to hear about what they find!
Later in the day on Sunday, we found some good rock outcrops near the Cricket stadium, and we climbed up to the top to get a good view. We found that the rocks lay flat, so we knew were standing on top of the middle of the anticline.
There were some little boys playing outside and they saw us way up on top of the hill and came to investigate. You can probably imagine how much we stand out – such strange foreign girls, dressed like men! We rarely see people here with closed shoes, let alone boots! As we continued working, more and more young children kept coming up the hill to join their friends.
Oh, and I almost forgot to mention we saw an elephant! (not wild, though.)
