Over time, pounding waves gradually widened a fracture in the rocks forming Cook's Chasm. The edge of the chasm was undercut, creating a cave. Finally, a hole or crack formed in the roof of the cave, setting the stage for the spouting horn.
Incoming waves funnel air and water into the cave, building pressure until the water explodes in a geyser-like spray. The sight and sound of the Spouting Horn resembles a whale exhaling, which is called a "blow" or...you guessed it... a "spout".
1) How old do you think the Spouting Horn is?
2) Do you think the Spouting Horn will blow it out, or erode until it falls through?
3) Describe the rock you find around the Spouting Horn?
4) Was it low tide or high tide when you visited?
5) How does the tide affect the ferocity of the Spouting Horn?
6) List two types of "Spray Zone" animals you will find here.
7) List two types of "Middle Tide" animals found here.
Post a picture of yourself with the Spouting Horn in the background.
