Now to let the pictures do the talking.
I knew I was at the right place when I saw this.:
I followed the trail to the Rock House by going along the upper edge. As I recalled it was a loop around with the path going along the upper edge and then looping back through the caves and then ending back at the parking lot. I knew there were hills to climb and thought it best to do it first while I was still rested from driving and not all tuckered out from hiking.
I did recall having to be very careful while walking along the edge because the drop-off is more severe than it appears at first.
You really couldn't call them faults because there was very little displacement along them but the formation would definitely have a crack running through it which would channel water also through it. The water would scour the cracks widening them with time so that they could become vary visible. Like this one.

Because of this weathering the assumption is that this rock formation was deposited in an intertidal area. From other things I've observed and read the Blackhand Sandstone formation is believed to be an ancient deltaic system.

I was surprised to see how much of a drop-off there still was after having climbed down to the rock house area.

The ceiling and floor are the two more resistant zones of the Blackhand sandstone while the middle section is the less resistant zone. There is a joint going the length of the ceiling that allowed the water into this area to weather it out. There is also small joints going into the side of it that allow light in and gives it an appearance of a Medieval church. Because of its nature the place has been used as a hide out for robbers and a settlement for Native Americans.

Here's one of the cross cutting joints that let the light into the area and giving it a reverent feeling to the place.
A different area that had opened up.
When I came out this is what you looked down on and you had to be very careful in picking up the trail again.
