    Geology and Filming in Mizoram

    In the small town of Kolasib, we stayed in Hotel Cloud 9. I had been told since I was a child that I was always off on Cloud 9 and now I was actually here. However, the electricity wasn’t for the first few hours, so showers were cold, but the dinner was hot.

    Tiger Footprints and Dhaka

    We finished our time in the Sundarbans with a silent boat ride in a tidal creek. The highlight was sets of fresh tiger footprints. We then had a long sail back to Dhaka with only one stop at a village. We then had a whirlwind tour of Old Dhaka with enough shopping to send the…

    Salt Kilns and Landscape Change in the Sundarbans

    Leaving Hiron Point, we headed east through the Sundarbans to Kotka. At Kotka the students had walks through the forest seeing deer, wild boar and monkeys, while a smaller group also sampled near a set of 300 year old salt making kilns for OSL dating. We managed to finish while the tide inundated the site.…

    Polder 32 and Hiron Point

    We visited Polder 32, an embanked island in the delta that was flooded for almost two years when the embankment failed in several places during Cyclone Aila. In addition to the problem of increased subsidence due to the embankment, the area struggles for fresh water. Then we sailed to Hiron Point, a forest station in…

    Working in the Bangladeshi Countryside

    After traveling by boat for two days, including crossing the Sundarban Mangrove Forest, we finally arrived in Khulna. We drove to the site of our compaction meter and separated into teams servicing the instruments, investigating agricultural practices, measuring arsenic in the well water and taking sediment samples for dating. We had finally started our work…

    Sailing Around Political Unrest in Bangladesh

    With the roads in Bangladesh hazardous to drive because of the ongoing political unrest, our undergraduate sustainable development class managed to proceed with our class trip over Spring Break by doing all travel by boat.

    Bricks, an Archeological Site and Home

    It was time to pack up and leave. Shofiq, who is from Sylhet, was dropped off near his home and the fellowship of the rocks was broken. We settled in for another long drive. We made an impromptu stop at one of the numerous brick factories scattered across Bangladesh. Here, the workers immediately started snapping…

    Field School: Sylhet Tectonics

    Most field trips have a “death march” hiking a long way through forest, swamps, hills or deserts to get to a remote outcrop. We have a “death bus ride” instead.

  • Field School: The Brahmaputra River

    Field School: The Brahmaputra River

    The first day was very light for the jet-lagged students, just a short introduction to the field school and some background, and then introductions all around as we started to get to know each other. The final group of nine students finally arrived around 9 p.m. They were the most worn-out, bedraggled bunch of travelers…
