Girl, you are lucky to have topsoil! We had some over in PA, but had that hard layer of clay and shale underneath. It was a start though and took amendments well. I could grow anything I wanted so long as it could take the climate and shorter season.
Not my pic below, but describes the area well. I've got a very similar but bigger bank to one side of my house where the house, driveway, and barn area was cut into the side of the ridge. When I had some driveway work done upon move in, the excavation opened up areas of much darker and redder clay. We also have more rocks and boulders here too, which were helpful to use down by the creek and for a natural retaining wall in front of the house. I've built that area up with compost and amendments so I could have flowerbeds.
It's all steep ridges and valleys here and any topsoil that was once here is long washed away from the hard rains so I had to have topsoil brought in, and I also made compost to create any garden areas.
I can't garden down by the creek because it floods a lot, but the soil down there is rather nice on top of the rockbed. If I still had my tractor I could bring some of that up here and I'd have wonderful raised beds. Anyway...here's what I'm working with now..
