A trip to Grotte Sainte-Anne

Last saturday I and other members of Schravelaar made a trip to Grotte Sainte-Anne. I heard from friends that there was a change in colors of formations in the cave. We went to have a look. The formations are on the ceiling of the cave (about 3,5 meters high above the water level ). During our trip we had to take a ladder with us for a closer look. Fortunately the entrance of the cave is wide enough to take the ladder inside. After 30 minutes we arrived at the spot. Indeed the formation is dark yellow now. Scientific research is necessary to determine it's origine. Down below some of the pictures I took together with Schravelaar.
