building stairs on steep rock

[nicklang907]

Hi,

I live in Canada (Quebec) and am wondering about building a small
staircase on a steep part of our land. The steep part is not too
long... maybe 10 feet, and it consists of soil with trees growing out
and i think there is rock under the soil. Basically what I'm
wondering is... how do you make stairs to cross this steep part?

I thought the best way would be to drill through the soil and then a
bit into the rock and set posts in concrete and then connect the
stairs to these posts. Is this feasible? Can any recommend books and/
or tools that would help with this?

Thanks!
