Today we headed to Roseau to obtain permits, and everyone got a chance to explore the city and chat with the locals. Then we drove to sulfur springs and took a steep uphill hike through the tropical forest. On the way up, Holli taught us the procedure for collecting water samples. The first stream we stopped at had sediment that was a deep brown reddish color due to hydrothermal alteration, and warm water. After that we moved to a site with lots of hydrothermally altered rocks that contained beautiful sulfur crystals that emitted a strong aroma. We continued hiking upwards to take additional water samples, have a lunch break, and collect gas samples.

After hiking down from sulfur springs, we moved to a hydrothermally altered debris flow scar to collect additional gas samples and discuss potential research project directions for other students. After that, we moved to Scotts head where we had a refreshing dip in the water and took in the view. On the way back, we stopped at an outcrop of lava, which is different from the typical block and ash outcrops that we usually see, and collected some hand samples to wrap up the day.
