A waterfall tumbles powerfully down a forested cliff, sending a steady sheet of water from the heights above to the rocky shore below. At low tide, the waterfall flows across the beach, where patches of vibrant green algae cling to the stones and sand, creating a striking contrast against the darker rocks. These green patches are more than just visually interesting—they indicate areas where freshwater from the waterfall mixes with tidal waters, and they are often sought out by kayakers as a natural source for replenishing their drinking water. In this way, the meeting of forest, cliff, and beach not only forms a dramatic landscape but also provides a crucial resource for those exploring the remote waterways of Glacier Bay.
