About 80/90 feet
There are lots of downhill sloping areas you walk through in addition to steps. Its not super deep. At one point on the tour they said imagine a school bus standing on end and that's how deep below the surface you are.
Yes it's not very deep probably like 80 foot but there are a lot of steps
About 80 feet. I believe they suggest deeper because there is a mountain/hill on top of canyon.
