There once stood on this spot seven of the worlds tallest trees, known as the 'Seven Sisters'. Their branches spread a cathedral-like canopy over the ground. At one time they were as popular a park attraction as the 
Hollow Tree.  In the 
1950s  they succumbed to disease and were cut down. 
Pauline Johnson described the grove in poetic detail, and wrote of a First Nations 
legend that was inspired by these impressive giants. I could be wrong, but it looks like one of them is still standing, judging by the burl on the tree at left.
