The Tower is 775 feet about the falls. I was glad we were able to do the revolving dining room verses the buffet which was suppose to not revolve. They have it timed so that while you wait on your food to come you get to see the falls. Then while you are eating and finishing up you are seeing whats to the north of the falls. Here's the pictures I took. (note: I had both my camera and cellphone with me and used both & was glad I did. The depth perception was different for them).
This is a good view of the caprock. The caprock, is more resistant and is the Lockport dolostone of Silurian age. This dolostone is what is so resistant and makes the falls as spectacular at they are.
You can see the depth perception difference between the camera and the cellphone. The top was the cell.
We did go down to the observation deck. It was nice to see how things were labeled for us.
