hopewell rocks • 16 comments • The 40-70 foot tall Hopewell Rocks, nicknamed Flowerpot Rocks, were formed due to tidal erosion. Fundy's tides are amongst the highest in the world and vary greatly within 24 hours. We left Moncton in the morning and drove to the area (with a few stops along the way). Because of the extreme tidal range, we were able to see things, that are normally under water, up close and walk around on the ocean floor. You can either stay for an entire tidal cycle in one day, or you can observe the times on their sign and come back the following day at the optimal time, which is what we chose to do. We returned the next day to see a difference of, apparently, 100 billion tons of water. I wondered if the effect would have been better had we seen the high tide prior to being able to walk around. It was still neat to see the spot we were standing less than 24 hours earlier be completely engulfed in water. - Mina
